oauth.authenticate() wraps the Authenticate OAuth endpoint, which validates the OAuth token passed in. If there is a current Member Session, the SDK will call the endpoint with the session token. This will add the new factor to the existing Member Session. If there is an intermediate session token, the SDK will call the endpoint with it. If the resulting set of factors satisfies the organization’s primary authentication requirements and MFA requirements, the intermediate session token will be consumed and converted to a Member Session. If not, the same intermediate session token will be returned.

If this method succeeds and the Member is not required to complete MFA, the Member will be logged in, granted an active session, and the .

If this method succeeds and MFA is required, the intermediate session token will be stored .

Parameters

oauth_token
string
required
The token to authenticate.
session_duration_minutes
number
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 in the browser cookies. 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.
locale
string
If the Member needs to complete an MFA step, and the Member has a phone number, this endpoint will preemptively send a one-time passcode (OTP) to the Member’s phone number. The locale argument will be used to determine which language to use when sending the passcode.The parameter is a IETF BCP 47 language tag, e.g. “en”.

Response

member_id

If the project is configured to use HttpOnly cookies, this field will always be an empty string.
member_device
object
If Protected Auth is enabled and returned fingerprinting results, this field will contain information about the member’s device attributes.
member_authenticated
boolean
Indicates whether the Member is fully authenticated. If false, the Member needs to complete an MFA step to log in to the Organization.
intermediate_session_token
string
The intermediate_session_token that should be passed into a secondary authentication endpoint, such as OTP authenticate, in order to receive a member session. The intermediate_session_token can also be used with discovery endpoints to join a different organization or create a new organization.If the member is fully authenticated, this field will be an empty string.
If the project is configured to use HttpOnly cookies, this field will always be an empty string.
primary_required
object | null
The types of primary authentication required.
mfa_required
object | null
The types of secondary authentication required to join the Organization.
member_device
object
If Protected Auth is enabled and returned fingerprinting results, this field will contain information about the member’s device attributes.
request_id
string
Globally unique UUID that is returned with every API call. This value is important to log for debugging purposes; we may ask for this value to help identify a specific API call when helping you debug an issue.
status_code
number
The HTTP status code of the response. Stytch follows standard HTTP response status code patterns, e.g. 2XX values equate to success, 3XX values are redirects, 4XX are client errors, and 5XX are server errors.
