Changes

Adds identifier verification (OTP) support to useAuth0().passkey for passkey signup, using @auth0/auth0-spa-js v2.29.0.

  • Step-up flow: when identifier verification is on for the connection, signup() throws PasskeyVerificationRequiredError before the passkey prompt. Its verificationRequired property lists the identifiers to verify (for example ['email']). Call the new passkey.continueSignup(codes) to finish.
  • Wrong OTP: continueSignup() throws a PasskeyGetTokenError with isRetryable: true. Retrying reuses the same passkey, so the user doesn't see a second biometric prompt.
  • State: continueSignup() updates isAuthenticated and user in the same way as signup() and login(). Errors are rethrown to the caller.
  • Exports: PasskeyVerificationRequiredError.
  • Dependency: @auth0/auth0-spa-js goes from ^2.28.2 to ^2.29.0.

No breaking changes. EXAMPLES.md has a new Identifier Verification section covering the flow, which errors can be retried, what happens on a page reload, and the phone deliveryMethod option.

Testing

Unit tests added in __tests__/passkey.test.tsx. Tested manually on a test tenant with email and phone OTP: a wrong code, then the right code, with continueSignup().

  • This change adds unit test coverage
  • This change has been tested on the latest version of the platform/language

Summary by CodeRabbit

  • New Features
    • Added support for continuing passkey signup after email or phone verification, including submitting verification codes and selecting text or voice delivery.
    • Exported PasskeyVerificationRequiredError so apps can detect when signup requires verification.
    • Successful signup continuation updates authentication state, with retry support for eligible errors.
  • Documentation
    • Expanded passkey examples with guidance on retryable errors, missing codes, and restarting signup if the pending session ends.

📝 Walkthrough

The passkey API now exposes continueSignup and PasskeyVerificationRequiredError. The provider forwards verification data to the client and dispatches an authentication-state update. Tests and examples cover signup verification and its error outcomes.

Changes: Passkey Identifier Verification

Layer / File(s) Summary
Expose signup verification continuation
src/auth0-context.tsx, src/index.tsx, package.json, __mocks__/@auth0/auth0-spa-js.tsx, __tests__/passkey.test.tsx
The context includes a continueSignup stub, the public API exports PasskeyVerificationRequiredError, and the SDK dependency and mock support the client method. Tests check API availability and error exports.
Complete signup verification
src/auth0-provider.tsx, __tests__/passkey.test.tsx
The provider forwards verification data to the client, converts failures with tokenError, and dispatches GET_ACCESS_TOKEN_COMPLETE with the current user. Tests cover signup and continuation, retryable and terminal errors, and authentication state.
Document identifier verification
EXAMPLES.md
The examples describe OTP verification during signup, retries, delivery methods, pending signup state, and related errors.

Merge Risk: 🔵 Low · up to 15ace

Users following the example may restart signup unnecessarily when MFA is required. Correct the example; the documented MFA guidance keeps this risk bounded.

Explanation

The title "feat: add passkey identifier verification with step-up pattern" matches the main change. The PR adds identifier verification (OTP) to passkey signup in useAuth0().passkey. It adds a PasskeyVerificationRequiredError, a passkey.continueSignup callback, the auth0-spa-js bump to 2.29.0, and EXAMPLES.md docs. The title is specific, uses a conventional commit prefix, and is under 70 characters. It does not name the continueSignup API, but it does not need to cover every detail.

- Line 1718: Update the complete passkey example to handle
PasskeyVerificationRequiredError, which is not caught by the existing
PasskeyError branch. Add a verification-required branch that collects codes from
error.verificationRequired and calls continueSignup(), or link directly to the
documented continuation flow; preserve the existing handling for other errors.
- Around line 1612-1617: Update the retry branch in the signup example to also
handle PasskeyError with code missing_verification_code from continueSignup().
Keep the current required identifiers for this case and enforce MAX_ATTEMPTS; do
not clear required or send the user to restart.

Review comments at @src/index.tsx:
- Line 87: Update the README API reference to document passkey verification,
including `useAuth0().passkey.continueSignup(codes)` and the public
`PasskeyVerificationRequiredError` export introduced in `src/index.tsx`.

🟡 Minor · Preserve the original passkey error when state synchronization… · auth0-provider.tsx:553-556

src/auth0-provider.tsx:553-556
🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Preserve the original passkey error when state synchronization fails.

client.getUser() can reject when the configured cache or localStorage read fails. Because passkeyContinueSignup awaits it in finally, that rejection replaces the original PasskeyError or PasskeyGetTokenError. The completion dispatch is also skipped, so callers can receive the cache error instead of the retryable passkey error and the provider state is not synchronized.

Suggested fix
       } finally {
-        dispatch({
-          type: 'GET_ACCESS_TOKEN_COMPLETE',
-          user: await client.getUser(),
-        });
+        try {
+          dispatch({
+            type: 'GET_ACCESS_TOKEN_COMPLETE',

🟡 Minor · Handle MfaRequiredError before the restart branch. · EXAMPLES.md:1618-1623

EXAMPLES.md:1618-1623
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Handle MfaRequiredError before the restart branch.

continueSignup() can throw MfaRequiredError with error.mfa_token. The current handler sends it to the catch-all branch, clears the required identifiers, and tells the user to restart.

Add an explicit MfaRequiredError branch before the catch-all branch. Start the MFA flow described in the existing MFA example with e.mfa_token. Keep the restart branch for other terminal errors.
