Authenticate - Stytch Docs

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 cookies will be minted and stored in the browser.

Parameters

token

string

required

The token to authenticate.

Configuration

object

required

Additional configuration.

Show properties

session_duration_minutes

int

required

Set the session lifetime to be this many minutes from now. This will return both an opaque session_token and session_jwt for this session, which will automatically be stored either in the browser cookies if you’re using our JavaScript SDK, or in the iOS Keychain/ Android SharedPreferences if you’re using one of our mobile SDKs. The session_jwt will have a fixed lifetime of five minutes regardless of the underlying session duration, and will be automatically refreshed by the SDK in the background over time. This value must be a minimum of 5 and may not exceed the maximum session duration minutes value set in the Frontend SDK page of the Stytch Dashboard. A successful authentication will continue to extend the session this many minutes.
