Auth

Twenty hooks covering every Firebase Auth client flow, plus the provider that holds them together.

Every Firebase Auth client flow, one hook each. They all follow the same contract, so learning one is learning the rest.

import {
  AuthProvider,
  useLogin,
  AUTH_ERROR_MESSAGES,
} from '@timonwa/firebase-hooks/auth';

AuthProvider / useAuth

The live user and custom claims for your whole tree, and the one place app-wide defaults live. Optional — hooks work without it.

useLogin

Email/password sign-in. The shortest path to seeing the result shape and onIdToken in action.

Signing in and out

Hook	What it does
`useLogin`	Email/password sign-in
`useSignup`	Signup with optional profile and verification email
`useLogout`	Sign-out, your server session cleared first
`useOAuthSignIn`	Any provider — popup or redirect, both halves handled
`useEmailLinkSignIn`	Passwordless magic link, no `window.prompt`
`usePhoneSignIn`	SMS code with a managed reCAPTCHA verifier
`useAnonymousSignIn`	Guest sessions, upgradeable later
`useCustomTokenSignIn`	Server-minted custom token

Passwords

Hook	What it does
`useSendPasswordResetEmail`	The forgot-password email
`useConfirmPasswordReset`	Complete a reset from the emailed code
`useUpdatePassword`	Change it, reauthentication built in

Email

Hook	What it does
`useSendEmailVerification`	The resend-verification button
`useVerifyEmail`	Apply the emailed code on mount
`useUpdateEmail`	Change it via verify-before-update

Account and linking

Hook	What it does
`useUpdateProfile`	Display name and photo URL
`useDeleteAccount`	Delete, with reauth and server cleanup
`useReauthenticate`	The recent-sign-in check, standalone
`useLinkProvider`	Add a sign-in method — upgrade a guest
`useUnlinkProvider`	Remove a sign-in method

Not covered yet

Multi-factor auth (TOTP and SMS enrolment/resolution) and multi-tenancy are planned for a later minor. The Admin SDK is server-side and out of scope — see Compatibility.
