feat(passkey): update documentation for passkeys with granular APIs by siddhikotak · Pull Request #1306 · auth0/auth0-react

siddhikotak · 2026-10-26T11:12:55Z

Description

Follow-up to #1303, which added getSignupChallenge, getLoginChallenge and getTokenWithPasskey to useAuth0().passkey without docs. This PR adds the docs and type exports so the granular passkey APIs are usable.

EXAMPLES.md: new "Granular Passkey APIs" section (signup and login), plus a granular identifier-verification example with OTP retry. The retry table, deliveryMethod, cancellation and error-handling notes now cover the granular methods.
Exports: re-exports PasskeySignupChallengeOptions, PasskeyLoginChallengeOptions, PasskeySignupChallenge, PasskeyLoginChallenge and PasskeyGetTokenOptions from @auth0/auth0-spa-js. This only adds exports.
JSDoc: the passkey doc comment now covers verification with the granular APIs.

Walkthrough

The pull request documents granular passkey signup and login flows, exports related option and challenge types, and adds tests for challenge state, token exchange, and verification retries.

Changes: Granular passkey APIs

Layer / File(s)	Summary
Challenge and token exchange API `src/index.tsx`, `EXAMPLES.md`, `__tests__/passkey.test.tsx`	The package exports passkey challenge and token option types. The documentation describes obtaining challenges, using browser credential APIs, and exchanging credentials. Tests check challenge state and token-exchange arguments.
Identifier verification and retry `EXAMPLES.md`, `src/auth0-context.tsx`, `__tests__/passkey.test.tsx`	The documentation describes collecting verification codes and retrying with the same credential and updated `authSession`. Tests check retry data and authentication after retry. The documentation also covers phone delivery methods and cancellation errors.

Priority: Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: Low · up to 4dd1c

Apps copying the first signup example may fail identifier verification. The detailed example provides a working path, but the first example should be corrected.

Description Check		Check skipped - CodeRabbit’s high-level summary is enabled.
Title check		The title accurately describes the documentation updates for granular passkey APIs. It does not mention the added type exports, but it remains clear and related to the main changes.
Docstring Coverage		Docstring coverage is inconclusive: files from earlier reviews still need to be rechecked within the check's analysis limits. Not blocking.

- Around line 1735-1737: Update the catch flow around PasskeyGetTokenError so a
PasskeyError with code missing_verification_code prompts for a corrected code
and retries with the same credential and authSession instead of ending the
granular flow; preserve the existing handling for other errors.
- Line 1755: Update the `missing_verification_code` row in the Passkey error
table to distinguish an empty code, which `getTokenWithPasskey()` rejects
locally, from an omitted identifier, whose code is sent to token exchange. Do
not claim the session remains unused for the omitted-code case.

Minor · Assert the create() result as PublicKeyCredential before passing it… · EXAMPLES.md:1721-1727

EXAMPLES.md:1721-1727
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Assert the create() result as PublicKeyCredential before passing it to getTokenWithPasskey().

navigator.credentials.create() returns Promise<Credential | null>. The if (!credential) check removes only null, so credential stays typed as Credential. getTokenWithPasskey() requires credential: PublicKeyCredential. Under strict TypeScript, this assignment fails to compile, so readers who copy the example get a type error.
Suggested fix
-    const credential = await navigator.credentials.create({
+    const credential = (await navigator.credentials.create({
       publicKey: challenge.publicKey
-    });
+    })) as PublicKeyCredential | null;

Looks good overall, thanks @siddhikotak! Just a few small doc suggestions.

yogeshchoudhary147 · 2026-10-27T03:35:04Z

Also, can we update the title to feat(passkey): export granular passkey types and add docs? #1303 already added the APIs, so the current title would show up twice in the changelog.
