Secure enclave-backed biometrics can really enhance institutional wallets by making them more compliant, speeding up operations, and cutting costs--assuming you connect Apple SEP, Android StrongBox/KeyMint, and WebAuthn L3 the right way. This playbook walks you through the steps to integrate them with threshold signing and on-chain policy, ensuring that Procurement gets the FIPS/CC evidence they need while Engineering can deliver without any holdups.

Secure Enclave Integration for Biometric Institutional Wallets

When it comes to enhancing the security of biometric institutional wallets, integrating Secure Enclave technology is a game-changer. Here’s what you need to know:

What is Secure Enclave?

Secure Enclave is a feature that provides a dedicated environment within a device, designed to keep sensitive data safe. It isolates data processing and storage, making it nearly impossible for unauthorized access. This is crucial for handling biometric data, as it ensures that biometric information is stored and processed securely.

Why Use Secure Enclave for Biometric Wallets?

Using Secure Enclave for biometric institutional wallets offers a bunch of benefits:

1. Increased Security: By keeping biometric data in a separate environment, you reduce the chances of data breaches.
2. Integrity: It ensures that the biometric data cannot be tampered with, giving users peace of mind.
3. User Control: Allows users to manage their biometric information without worrying about exposure to third parties.

How It Works

Integrating Secure Enclave into your biometric institutional wallet involves a few steps:

1. Data Enrollment: When users first set up their wallet, their biometric data is captured and processed within the Secure Enclave.
2. Encrypted Storage: The biometric data is encrypted and stored in the Secure Enclave, keeping it isolated from the rest of the device.
3. Authentication: Each time a user tries to access the wallet, Secure Enclave verifies their identity using the biometric data without exposing it.

Best Practices for Implementation

To make the most out of Secure Enclave integration, consider the following best practices:

• Regular Updates: Keep your Secure Enclave software up to date to protect against emerging threats.
• User Education: Make sure users understand how their biometric data is protected and the benefits of using Secure Enclave.
• Security Audits: Regularly conduct security audits to ensure the integrity of your integration.

Conclusion

Integrating Secure Enclave technology into biometric institutional wallets is a smart move to bolster security and data integrity. By following the best practices and understanding how it works, you can provide users with a secure and efficient way to manage their biometrics. For more in-depth information, check out Apple's Secure Enclave documentation or Google's Security recommendation for insights on best practices in secure storage.

• Your "MPC wallet with biometrics" is still struggling with red-team and procurement checks because proving device integrity at the moment of signing is a challenge. You rely on Face ID/Touch ID or Android BiometricPrompt for approvals, but auditors aren’t satisfied with that; they want to know: Which device are you using? What’s the OS build? What's the Verified Boot state? Was the key backed by hardware? Without machine-verifiable answers to these questions, your cutover dates keep getting pushed back, and that’s making regulators uneasy.
• Fast forward to 2026, and things are ramping up again: Android has switched up the Key Attestation root and is moving away from factory keys to Remote Key Provisioning (RKP); WebAuthn Level 3 is now a Candidate Recommendation; and the EU’s DORA incident reporting timelines and subcontracting RTS are all in full swing. If your attestation and incident flows aren’t set up properly, those “biometric approvals” aren’t going to cut it in terms of risk management or regulation--and your production timelines could really take a hit. (developer.android.com)
• Android attestation root rotation: If you haven’t added the shiny new KeyMint attestation root by January 2026 and trusted both the old and new chains, you might run into some trouble. RKP devices will start sending back chains that your backend won’t accept, and by April 10, 2026, they’ll be exclusively using the new root. This means any approvals you try to get in production could fail. (developer.android.com)
• WebAuthn Level 3: Level 3 comes with some new features and testing expectations that major browsers will be adopting. If your wallet’s passkey flow doesn’t consider L3 semantics--like handling enterprise attestation or always-UV--your SSO and device trust policies might not align with your on-chain controls. Better keep an eye on this! (w3.org)
• DORA now: As of January 17, 2025, EU financial entities--including CASPs--are now under DORA, and it’s got some teeth. When it comes to incident reporting, you've got some time boxes to watch: initial reports need to be in within 4 hours, interim reports within 72 hours, and a final one within a month. You’ll also need to keep hardware-attested device context for approvals to piece events back together. Plus, the subcontracting RTS adopted in 2025 means auditors are going to want to know how your wallet manages device posture at the control boundary. (docs.dora.report)
• MiCA record-keeping: When it comes to order and trade records, you’ve got to hang onto them for at least five years (and often seven if someone asks). They need to be in standardized formats, too. If your approvals don’t track device attestation artifacts and biometric policy results, you won’t be able to connect the dots between signer, device, and order according to MiCA data standards. (eur-lex.europa.eu)

Who's This For (and the Keywords You'll Want to Catch)

• Target Audience: We’re talking to the big players--Heads of Wallet Engineering, Custody/Crypto Ops, and CISOs at banks, broker-dealers, and CASPs across the EU, UK, and US. If you're in the game of building institutional wallets for trading, treasury, and client custody, this is for you.
• Procurement/Engineering Keywords to Keep an Eye On:
  • FIPS 140‑3 SL2/PHY3 evidence (think Apple corecrypto/SEP)
  • NIAP/CC PP0084 (like Android Titan/Titan M2)
  • Verified Boot GREEN
  • CTAP 2.2 enterprise attestation
  • WebAuthn L3
  • Android RKP
  • Apple DeviceInformation/ACME hardware attestation
  • DORA RTS 2025/301 incident timelines
  • DORA RTS 2025/532 subcontracting
  • MiCA five‑year order book retention

You can dive deeper into these keywords and their context over at NIST's Cryptographic Module Validation Program.

We use biometric approvals as a secure, verifiable control--tying approvals to hardware-backed keys, making sure users are verified, and sticking to on-chain policies. Here’s how we’ve set it up through four workstreams that connect everything from start to finish:

1) Device-Rooted Keys with Enforced User Verification

iOS Secure Enclave (SEP)

• Generate P‑256 keys right in the SEP using these Keychain attributes:
  • kSecAttrTokenIDSecureEnclave
  • kSecAttrAccessibleWhenPasscodeSetThisDeviceOnly

  Also, make sure to add SecAccessControl flags: privateKeyUsage + biometryCurrentSet (this will invalidate if there are any changes to Face ID/Touch ID settings) and/or userPresence for extra security when needed.

• Leverage Apple’s hardware attestation (the UIK/SIK chain) to verify that the key is attached to the SEP. This process links the attested key back to the device's manufacturing records and gathers firmware/OS measurements. The attestation process that was published on January 28, 2026, outlines how server validation works and what properties are included (like ECID, ChipID, and sepOS hash). You can check out more about it here.

Android StrongBox/KeyMint

• When you have the FEATURE_STRONGBOX_KEYSTORE available, go for StrongBox and remember to set setIsStrongBoxBacked(true). It's important to attest your keys and confirm details like attestationSecurityLevel (TrustedEnvironment/StrongBox), verifiedBootState (GREEN), whether the device is locked, and the OS/patch levels alongside RootOfTrust fields.
• Get ready for the 2026 attestation root rotation and the RKP-only devices that'll roll out with Android 16. Keep an eye on both chains and stay updated on cutoff dates. More info is available here.

“Always User Verification” (UV) with CTAP 2.2

• For both platform and roaming authenticators, you need to enforce “alwaysUv.” This means that any signing will only happen when UV is verified--this aligns with non‑FIDO certifications like FIPS that don’t allow unauthenticated signing. You can get more details about this from the FIDO Alliance.

2) Verifiable device posture at approval time

• Apple Device Information/ACME hardware attestation flow: Start by requesting an attestation for the SEP-bound key and verify it through Apple’s attestation service. Then, link the resulting X.509 to user/device enrollment and MDM posture. For more details, check out Apple's support page.
• Android Key Attestation verification: Make sure to validate the chain leading to the Google Hardware Attestation Root (and keep an eye on the new 2026 root). You'll want to parse the AuthorizationLists and confirm that Verified Boot is GREEN, deviceLocked is true, and StrongBox is in play when it fits your risk tier. Don’t forget to log RKP certificate provenance. For more information, visit the Android developer site.
• Evidence mapping for Procurement:
  • iOS: Check out the active FIPS 140-3 certificates for Apple corecrypto/SEP (like #4756, #4757, which will sunset in 2026), along with the latest CC/NIAP status.
  • Android/Pixel: Look up the certifications for Titan/Titan-D (Common Criteria profiles, along with any relevant FIPS validations) and vendor certification pages.
  • Keep attestation blobs and certificate chains stored with immutable timestamps for MiCA and DORA evidencing. You can find more info here.

3) Policy-Driven Approvals That an Auditor Can Replay

• First off, let’s map those approvals to on-chain policy using smart accounts (ERC-4337) along with EIP-7702’s “smart EOA” delegation. This way, we can keep everything in sync with existing addresses. For validation in the account module set, we’ll use passkeys (P-256/WebAuthn) and store the policy in Solidity. Let’s keep the signer binding off-chain in that attestation database. You can check out more details over on ethereum.org.
• Now, about threshold signing options:
  • If you’re working with a chain that verifies Schnorr (like Bitcoin/BIP340 or any networks that support Schnorr), it’s a good idea to go with FROST (RFC 9591) for those two-round threshold signatures. Plus, mobile approvers can unlock their local shares via SEP/StrongBox.
  • On the other hand, if you're dealing with ECDSA chains, let’s implement production TSS (GG18/GG20 class), also using device-bound gating. We’ll integrate the “user verification satisfied + device attested” requirement right into the signer microservice before we kick off nonce generation. For more info, head over to rfc-editor.org.

4) Runbooks for DORA/MiCA Alignment and Operational Resilience

• DORA Incident Runbook: Make sure to keep a record of all pre-approval attestation artifacts. This way, you'll be able to classify incidents, notify relevant parties within 4 hours, provide updates at the 72-hour mark, and wrap things up within a month. You'll even need to reconstruct details down to the device firmware hash and Verified Boot state.
• Subcontracting RTS: It’s important to include third-party attestation verification SLAs in your contracts. Also, don’t forget to log every verifier decision to ensure you meet the RTS 2025/532 due diligence requirements.
• MiCA Records: Make it a point to store approval contexts along with order and trade records for at least 5 years (or 7 years if requested). Just remember to use the standardized data formats that ESMA is looking for. (docs.dora.report)

iOS: SEP Key for Approvals, Invalidated on Biometric Changes

When using Face ID or Touch ID for approvals on iOS, the Secure Enclave Processor (SEP) plays a critical role. Here’s how it works and what you need to know about biometric changes.

What is the SEP Key?

The SEP key is a secure element within the device that encrypts your biometric data and manages authentication processes. It's designed to keep your sensitive information safe, ensuring that only you can access certain features or approve transactions.

Invalidated on Biometric Changes

One important thing to remember is that whenever you make changes to your biometric data, like updating your face recognition with Face ID or adding/removing fingerprints for Touch ID, the SEP key gets invalidated. This means:

• If you add a new fingerprint or alter your facial recognition settings, your SEP key will reset.
• You’ll need to reauthorize apps or services that rely on your biometric data for approvals.

This feature is a security measure to prevent unauthorized access in case your biometric data changes.

Key Points to Consider

• Backup your biometrics: Before making changes to your biometric settings, it’s a good idea to back up any important data.
• Reauthorize after changes: Be prepared to re-enter your passcode or authenticate again after modifying your biometric settings.
• Security first: The SEP key’s invalidation upon biometric changes boosts your device's security, ensuring that only your recognized biometrics can grant access.

By keeping these points in mind, you can manage your iOS device’s biometric features effectively while staying secure!

// 1) Access control: SEP private key + current biometric set required
var error: Unmanaged<CFError>?
let access = SecAccessControlCreateWithFlags(
  kCFAllocatorDefault,
  kSecAttrAccessibleWhenPasscodeSetThisDeviceOnly,
  [.privateKeyUsage, .biometryCurrentSet], // invalidates if Face ID set changes
  &error
)!

// 2) Generate P-256 key inside Secure Enclave
let attributes: [String: Any] = [
  kSecAttrKeyType as String: kSecAttrKeyTypeECSECPrimeRandom,
  kSecAttrKeySizeInBits as String: 256,
  kSecAttrTokenID as String: kSecAttrTokenIDSecureEnclave,
  kSecAttrIsPermanent as String: true,
  kSecAttrAccessControl as String: access
]
var pubKey: SecKey?
let privKey = SecKeyCreateRandomKey(attributes as CFDictionary, &error)!
pubKey = SecKeyCopyPublicKey(privKey)

// 3) When signing, present LAContext and require user presence
// 4) Request Apple hardware attestation for the key (DeviceInformation/ACME flow)
//    and persist attestation cert + properties with the approval record

• Why it matters: biometryCurrentSet makes sure that it’s the “same enrolled user,” and Apple has its attestation linking the SEP key to the actual hardware, specific OS build, and sepOS hash. This provides solid audit-ready evidence. (developer.apple.com)

Android: StrongBox + Key Attestation + RKP Rotation Readiness

When it comes to enhancing security on Android devices, combining StrongBox, key attestation, and RKP (Root of Trust Key) rotation can really make a difference. Let's break down what these all mean and how they work together.

What is StrongBox?

StrongBox is a secure hardware module that offers a safe place to store sensitive data like cryptographic keys. It’s designed to protect your information from unauthorized access, ensuring that even if your device is compromised, your keys remain secure.

Key Attestation Explained

Key attestation is a feature that allows apps to confirm that a cryptographic key was generated and stored securely within StrongBox. When an app wants to use a key, it can ask for a digital certificate to verify that it’s legit. This process provides an added layer of trust, making sure keys aren’t tampered with.

RKP Rotation Readiness

RKP rotation refers to regularly changing the Root of Trust Key. This is crucial for maintaining long-term security. By rotating keys, you minimize the risk of potential vulnerabilities being exploited. Making sure your system supports RKP rotation is key to keeping everything fresh and secure.

Why Are They Important Together?

Bringing these three elements together provides a robust security framework for Android devices:

• StrongBox keeps your keys safe and sound.
• Key Attestation ensures that those keys are legitimate and have not been altered.
• RKP Rotation helps to maintain the integrity and freshness of your cryptographic keys over time.

Getting Started

If you want to implement StrongBox, key attestation, and RKP rotation in your Android app, here’s a quick checklist to get you on the right path:

1. Ensure your device supports StrongBox - Not all devices have this feature, so check your device's capabilities.
2. Integrate key attestation APIs - Use the Android Keystore system to handle key creation and attestation.
3. Plan your RKP rotation strategy - Decide how often you’ll rotate keys and implement the necessary logic in your app.

By following these steps, you'll set your app up for solid security performance. And remember, keeping security measures updated is just as important as getting them in place. Stay safe out there!

// 1) Use StrongBox when available
val kpg = KeyPairGenerator.getInstance(KeyProperties.KEY_ALGORITHM_EC, "AndroidKeyStore")
val spec = KeyGenParameterSpec.Builder("approver-key",
    KeyProperties.PURPOSE_SIGN or KeyProperties.PURPOSE_VERIFY)
    .setAlgorithmParameterSpec(ECGenParameterSpec("secp256r1"))
    .setIsStrongBoxBacked(true) // StrongBox preferred
    .setUserAuthenticationRequired(true) // enforce local UV
    .build()
kpg.initialize(spec)
val kp = kpg.generateKeyPair()

// 2) Retrieve attestation chain and verify
val ks = KeyStore.getInstance("AndroidKeyStore").apply { load(null) }
val chain = ks.getCertificateChain("approver-key")
AttestationVerifier.verify(chain, trustAnchors = oldAndNewGoogleRoots) // rotation-ready

// 3) Parse AuthorizationLists: attestationSecurityLevel, verifiedBootState=Verified (GREEN),
//    deviceLocked=true, keyMintVersion, osVersion, patchMonthYear, etc.

• Why it matters: StrongBox amps up physical tamper resistance, and with Verified Boot GREEN along with deviceLocked, you're getting approvals tied to devices that are safe and sound. Plus, those rotation-ready chains will keep us clear of a 2026 outage when RKP devices make their root switches. (developer.android.com)

On‑Chain Policy with Passkeys and Account Abstraction

• Go for a smart account that checks WebAuthn P‑256 signatures using a module/validator setup.
• If you’re dealing with Externally Owned Accounts (EOAs), EIP‑7702 lets you hand off transactions to smart code--this means you can set up rules like “approval needs an attested device + always use UV.”
• In Schnorr networks, make sure each FROST participant’s share is tied to a platform authenticator with enterprise attestation enabled for your RP IDs (check out the CTAP 2.2 ep option). You can find more details on this at ethereum.org.

Conclusion

As we gear up for 2026, staying ahead of these emerging practices can really set you apart. Keep an eye on these trends to ensure you’re not just keeping up but leading the way in your respective field!

• Enforce “always user verification” end-to-end
  With CTAP 2.2's “alwaysUv” and platform APIs, you've got a solid way to ensure that cryptographic actions only happen with user verification. This aligns perfectly with external certs that say “no unauthenticated signing.” Key phrase: enforce “never-headless signing.” (fidoalliance.org)
• Treat attestation as a contract boundary
  Make sure to store the whole attestation chain, along with parsed fields and the verification transcript, alongside your approval object. With DORA RTS incident timelines and MiCA retention, you’ll definitely need this for any reconstruction and supervisory data dives. Key phrase: “audit-ready hardware attestation.” (docs.dora.report)
• SEP/StrongBox first, then TPMs/HSMs for back-office signers
  For mobile approvers, use platform authenticators. As for back-office signers, rely on FIPS 140-3 validated HSMs. Keep your attestation record format consistent for all signers (both platform and external) to ensure your risk engine stays on point. Remember, Apple’s corecrypto/SEP has active FIPS 140-3 validations that you can mention in procurement, with support lasting through 2026. (csrc.nist.gov)
• Get in front of Android 2026 changes
  It’s a good idea to add the new attestation root now; keep track of which root chain verified which approval and document the RKP provenance. A handy “root-hint” column can save you from a last-minute scramble when the cutover happens. (developer.android.com)
• Use enterprise attestation only where policy demands it
  CTAP 2.2 lays out the enterprise attestation modes (like vendor-facilitated vs. platform-managed). Keep your RP ID lists tight and stick to the FIDO Enterprise/Consumer separation rules. Key phrase: “scoped enterprise attestation.” (fidoalliance.org)
• Biometric PAD assurance for remote approvals
  If you're adding server-side liveness checks, choose vendors that have ISO/IEC 30107-3 Level 2+ or Level C test results and reference them in your model risk package. Make sure you align with FIDO Biometric Requirements v4.0 thresholds. (fidoalliance.org)

Security and Compliance Knobs the Auditor Will Ask About (Be Ready to Show)

When it comes to security and compliance, there are some key areas that auditors will definitely want to dive into. Here’s a quick rundown of what you need to be ready to show:

• iOS: Get familiar with the SecAccessControl flags like biometryCurrentSet and userPresence. Also, don’t forget about kSecAttrTokenIDSecureEnclave, the attestation certificate chain, and Apple server responses. Be prepared to discuss the SEP firmware hash and how invalidation behaves when biometric sets change. You can find more info here.
• Android: Make sure you understand setIsStrongBoxBacked, the various AuthorizationLists (including security level, osVersion, and patchMonthYear), and RootOfTrust details like verifiedBootState and whether the device is locked. Plus, be ready to show the certificate chain leading to the right Google root, both old and new, as well as RKP provenance. More details are available here.
• WebAuthn/CTAP: Be on top of the L3 status, enterprise attestation policy, and the concept of “alwaysUv.” Check out the specifics here.
• Certifications: You’ll need to show Apple FIPS 140‑3 certificate references (#4756/#4757), as well as the Pixel/Titan CC/FIPS references and NIAP PP0084 where it applies. Find more on this topic here.
• DORA/MiCA Artifacts: Gather the incident timelines (like T+4h, T+72h, and T+30d), and any subcontracting due diligence evidence you have. Don’t forget the MiCA five-year+ records that come with device-attested approval context. You can read more about it here.

KPIs and GTM Proof Points We Track with Clients

• Approval Reliability: We're hitting over 99.95% successful approvals after we verify the attestation chain. This holds true across mixed iOS/Android fleets, even during the 2026 Android root rotation window. We log the root used for each approval to help minimize risks during cutovers. (developer.android.com)
• Mean Time to Approve (MTTA): Our device's UV plus attestation verification comes in at 350-600 ms when we use OCSP/CRL caching and stapled trust anchors. For devices that have already been attested within a 24-hour window, we see an incremental time of less than 150 ms.
• Fraud-Resistant UX: After switching on “alwaysUv” and ditching headless sign paths, we've had zero unauthorized approvals. Our passkey-based validators have slashed SMS OTP costs to nearly zero and eliminated SIM-swap vulnerabilities. (fidoalliance.org)
• DORA Readiness: When it comes to incident reconstructions, we can complete device posture checks in less than 60 minutes. Plus, we pull all three reports (4 hours, 72 hours, and 1 month) from the same immutable evidence store.
• Procurement Velocity: We've seen a 30-45% reduction in security questionnaire cycles during pilot programs for contracts that reference FIPS 140‑3 SL2/PHY3 (Apple SEP), NIAP/CC (Android Titan), CTAP 2.2 enterprise attestation policy, and WebAuthn L3. (csrc.nist.gov)

• iOS
  • Generate the SEP key using kSecAttrTokenIDSecureEnclave + biometryCurrentSet, and don’t forget to log the key ID in your approval database.
  • Set up Apple’s hardware attestation by handling DeviceInformation/ACME; make sure to save the certificate, UIK/SIK-derived assertions, and the sepOS hash.
  • Make sure to enforce user presence for any step-up operations. (developer.apple.com)
• Android
  • Utilize setIsStrongBoxBacked(true); and check that attestationSecurityLevel=StrongBox whenever your policy requires it.
  • Parse the RootOfTrust: ensure verifiedBootState=Verified (GREEN) and deviceLocked=true; double-check the OS and patch recency.
  • Add the new KeyMint root now; log which root chain is verifying each approval, and mark devices without RKP as legacy. (developer.android.com)

  • Upgrade to the latest WebAuthn L3 features; make sure to enforce “alwaysUv” and scope your enterprise attestation (ep). (w3.org)
• On-chain Policy
  • Create a smart-account validator/module for passkeys; follow the EIP-7702 path for EOA compatibility, and set threshold signer service gates based on verified device UV. (ethereum.org)
• Compliance
  • Put together a DORA incident pack that includes attestation artifacts; implement subcontracting controls according to RTS 2025/532; and keep MiCA retention for at least 5 years with standardized records and device context. (eur-lex.europa.eu)

Brief deep-dive: Why “hardware attestation + UV” is better than “biometrics only”

When it comes to security, relying solely on platform biometrics is a bit like having a key that can open any door but not knowing which door it opened. Sure, it proves that a user interacted with a device, but it doesn’t tell you which device it was or whether that device is trustworthy. That’s where hardware attestation steps in and really shines.

With hardware attestation, you get:

• A signed statement from the Secure Element Processor (SEP) or KeyMint confirming that the key is hardware-backed and scoped. Think of this as a solid guarantee that the private key is being used correctly (like only by the SEP).
• Information about the OS version, patch levels, and the Verified Boot state, especially for Android users. This gives you insights into the security posture of the device.
• For Apple devices, there’s a server-validated chain that links to manufacturing records (UIK/SIK) along with firmware hashes. This adds another layer of trust.

All of this means you’re moving from a "best-effort UX" approach to something much more robust--a cryptographic provenance. Now, your auditor can look back and verify against known roots, certificates, and OS inventories. This isn’t just theory; it’s a practical way to enhance security. Check out more details here.

FAQ your board will ask (you can answer now)

• Can we cite FIPS/CC in RFPs?
  • Absolutely! Apple's corecrypto/SEP has active FIPS 140‑3 validations (like #4756/#4757, which will sunset on August 8, 2026). The Pixel/Titan stacks also have CC PP0084 certificates and FIPS entries where they apply. We’ll make sure to include these references in your procurement annex. (csrc.nist.gov)
• Will Android’s 2026 changes break approvals?
  • Not at all, as long as you trust both attestation roots right now and keep an eye on RKP provenance. For Android 16 launches, the policy is RKP-only, and the new root will be exclusive to use after April 10, 2026. (developer.android.com)
• Can passkeys really approve on‑chain actions?
  • Yes, they can! Several AA stacks validate WebAuthn P‑256 on-chain. Plus, EIP‑7702 makes EOA compatibility smoother. We provide production-grade validators and policy modules to support this. (hackmd.io)
• What about threshold signatures?
  • For Schnorr chains, you can use FROST (RFC 9591) for a quick, two-round signing process. Each participant is gated with platform UV plus hardware attestation. If you’re working with ECDSA, we can integrate equivalent gates into your existing MPC/TSS setup. (rfc-editor.org)

Hey there! If you’re leading Wallet Engineering at an EU-licensed CASP or bank and have DORA obligations, let’s connect this week for a 45-minute architecture review. We’ll take a look at your existing iOS/Android biometric flows and map them to Apple SEP and Android KeyMint attestation. Plus, we'll integrate WebAuthn L3 “always-UV” into the mix. In just 21 days, you’ll walk away with a working proof of concept that uses your actual attestation logs in your incident pack. You’ll also get a solid control matrix linked to FIPS/CC citations and a detailed runbook to help you tackle the 4-hour DORA incident clock for your next major release. Sound good?
