Authenticate

Authenticate

The Authenticate method wraps the authenticate Magic Link API endpoint which validates the magic link token passed in.

If this method succeeds, the user will be logged in, granted an active session, and the session data will be persisted on device.

You can listen for successful login events anywhere in the codebase with the stytch.session.onChange() method or useStytchSession hook.
