Why

revokeCurrentBiometricCredential() found the credential through the same selector that sign-in uses. That selector drops any credential the device can't use for a biometric check right now. So turning biometric sign-in off returned success without revoking anything when biometrics were unenrolled or the local key was gone. The server credential stayed active. When the key was missing, the selector also deleted the local record, so nothing on the device pointed to that server credential anymore.

Revoking doesn't sign anything, so it shouldn't depend on biometric capability.

What changed

• revokeCurrentBiometricCredential() looks up the newest local record for this app and user with candidateLocalCredentials, then revokes it.
• If the server returns resource_not_found, the method deletes the local record and succeeds. This keeps the old cleanup for credentials already revoked elsewhere, such as from the Dashboard.

Scope

• Covers revokeCurrentBiometricCredential() only. revoke(id), sign-in, and availability are unchanged. The public API signature is unchanged (apiCheck passes).
• This matches fix(biometric-credentials): revoke current device credential without a usable key clerk-ios#672 and feat(expo): add revokeCurrentDeviceCredential to biometric credentials hook javascript#10143. The method name still differs from revokeCurrentDeviceCredential on iOS and Expo. A rename would be a public API change, so it's left for a separate PR.

Blast Radius

This only affects revokeCurrentBiometricCredential() and the biometric toggle in UserProfileBiometricCredentialViewModel, which calls it. Revocation now also works when the Dashboard feature flag is off. The server still authorizes the call.

Verification

• Three new tests in BiometricCredentialsTest: biometrics unsupported, local key missing, and credential already revoked on the server. All three failed on main. In the first two, revoke was never called. In the third, the 404 came back as a failure. All three pass now.
• ./gradlew spotlessCheck detekt :source:api:apiCheck :source:api:testDebugUnitTest: 901 tests pass, and the format, lint, and API checks pass.

Summary by CodeRabbit

• Bug Fixes
  • Revoking the current biometric credential now succeeds when no local credential is available or the credential has already been revoked on the server.
  • When the server reports that the credential cannot be found, its stale local record is cleared. Other revocation errors continue to be reported.

📝 Walkthrough

Walkthrough

The revocation method selects the first locally stored credential. It returns success when no local candidate exists or when the server reports resource_not_found; in the latter case, it deletes the local credential. Other failures are returned unchanged.

Changes

Biometric credential revocation

Layer / File(s)	Summary
Select and revoke the local credential source/api/src/main/kotlin/com/clerk/api/biometriccredential/BiometricCredentials.kt, source/api/src/test/java/com/clerk/api/biometriccredential/BiometricCredentialsTest.kt	The method selects the first local candidate and handles resource_not_found by deleting the local credential and returning success. Tests cover empty supported biometric policies, a missing local key, and the not-found response. The test helper now configures the revoke result and local key presence.

Merge Risk: 🔵 Low · up to 5fa82

If local deletion fails after the server reports the credential gone, revocation appears successful but leaves a stale local record. This is a bounded cleanup risk to fix or explicitly accept before merging.
