PASSKEYS ON TOP OF FIREBASE AUTHENTICATION
Add passkeys to Firebase Auth
Firebase Authentication does not ship a passkey provider, so the WebAuthn ceremony has to live beside it. Corbado runs that ceremony and hands the result back, leaving Firebase as your system of record.
What Firebase teams need beyond passkey APIs
Keep your IdP
Firebase stays the system of record while Corbado adds passkey-specific analytics and rollout controls on top.
Govern rollout
Phase passkeys by cohort, app surface, region or device profile instead of forcing a one-shot launch.

Get passkey journey visibility and reporting that default IdP dashboards do not expose.
KEEP FIREBASE AS THE SYSTEM OF RECORD
Verify the passkey, then mint your Firebase session
The client runs the passkey ceremony, your backend verifies the signed response and delegates session creation to Firebase with a custom token. Your user records, claims and security rules stay exactly where they are.
Firebase
// 1. Browser or app completes the passkey ceremony
const signedPasskeyData = await corbado.completeLogin();
// 2. Your backend verifies it, then delegates the session to Firebase
const { userId } = await corbado.verify(signedPasskeyData);
const firebaseToken = await admin.auth().createCustomToken(userId);
// 3. The client signs in to Firebase as usual
await signInWithCustomToken(getAuth(), firebaseToken);
Know whether the Firebase passkey path is actually working
Enabling passkeys is the easy half. This guide covers the adoption, fallback and error signals that tell you whether users are really getting through.
PASSKEYS ROLLOUT OPERATIONS
What enterprise teams need in production
Passkey APIs are only one layer. Enterprise rollouts also need governance, investigation workflows and reporting once real users hit production traffic.
Passkey journey visibility
Inspect registration, sign-in, recovery, fallback and drop-off patterns across real customer journeys.
Rollout governance
Phase passkeys by cohort, device, browser or market and keep kill-switches ready when rollout conditions change.
Support investigation
Move from a vague ticket to one exact failing path instead of stitching together logs from multiple tools.
Existing stack compatibility
Keep your current IdP, session model and application flows while adding passkey-specific coverage on top.
Device readiness
Track browser, OS, authenticator and platform drift before rollout issues become expensive support queues.
Stakeholder reporting
Share adoption, failure patterns and business impact with IAM, product, security and support teams.

PASSKEY INTEGRATION RESOURCES FOR FIREBASE AUTHENTICATION
Firebase
Use these to wire the passkey ceremony to Firebase and to check the rollout once it is live.
About Corbado
Corbado is the Passkey Intelligence Platform for large-scale CIAM teams running consumer authentication. We help you see what IDP logs and generic analytics tools can't: where passkeys, passwords, OTP, social login and fallback journeys succeed, stall or fail, which devices and browsers create friction, and when an OS update silently breaks login. Two products: Corbado Observe layers process mining and observability across authentication journeys. Corbado Connect adds managed passkeys with analytics built in alongside your IDP. VicRoads runs passkeys for 5M+ users with Corbado (+80% passkey activation). Talk to a Passkey Expert →
Keep Firebase, add the passkey layer
Run the passkey ceremony alongside Firebase Authentication and see adoption, fallback and errors per cohort before you widen the rollout.
- Firebase stays the system of record
- No user migration required
- Adoption and fallback visible per cohort
