SMS OTPs may not be used as a primary authentication mechanism. They can be used to complete an MFA requirement, or they can be used as a step-up factor to be added to an existing session. This endpoint verifies that the one-time passcode (OTP) is valid and hasn’t expired or been previously used. OTP codes expire after two minutes. A given Member may only have a single active OTP code at any given time. If a Member requests another OTP code before the first one has expired, the first one will be invalidated. Exactly one of intermediate_session_token, session_token, or session_jwt must be provided in the request. If an intermediate session token is provided, this operation will consume it. Intermediate session tokens are generated upon successful calls to primary authenticate methods in the case where MFA is required, such as email magic link authenticate, or upon successful calls to discovery authenticate methods, such as email magic link discovery authenticate. If the Organization’s MFA policy is REQUIRED_FOR_ALL, a successful OTP authentication will change the Member’s mfa_enrolled status to true if it is not already true. If the Organization’s MFA policy is OPTIONAL, the Member’s MFA enrollment can be toggled by passing in a value for the set_mfa_enrollment field. The Member’s MFA enrollment can also be toggled through the Update Member endpoint. Provide the session_duration_minutes parameter to set the lifetime of the session. If the session_duration_minutes parameter is not specified, a Stytch session will be created with a duration of 60 minutes.

Authorizations

​
Authorization
string
header
required

Basic authentication header of the form Basic <encoded-value>, where <encoded-value> is the base64-encoded string username:password.

Body

application/json

Request type

​
organization_id
string
required

Globally unique UUID that identifies a specific Organization. The organization_id is critical to perform operations on an Organization, so be sure to preserve this value. You may also use the organization_slug or organization_external_id here as a convenience.

​
member_id
string
required

Globally unique UUID that identifies a specific Member. The member_id is critical to perform operations on a Member, so be sure to preserve this value. You may use an external_id here if one is set for the member.

​
code
string
required

The code to authenticate.

​
intermediate_session_token
string

The Intermediate Session Token. This token does not necessarily belong to a specific instance of a Member, but represents a bag of factors that may be converted to a member session. The token can be used with the OTP SMS Authenticate endpoint, TOTP Authenticate endpoint, or Recovery Codes Recover endpoint to complete an MFA flow and log in to the Organization. The token has a default expiry of 10 minutes. It can also be used with the Exchange Intermediate Session endpoint to join a specific Organization that allows the factors represented by the intermediate session token; or the Create Organization via Discovery endpoint to create a new Organization and Member. Intermediate Session Tokens have a default expiry of 10 minutes.

​
session_token
string

A secret token for a given Stytch Session.

​
session_jwt
string

The JSON Web Token (JWT) for a given Stytch Session.

​
session_duration_minutes
integer<int32>

Set the session lifetime to be this many minutes from now. This will start a new session if one doesn't already exist, returning both an opaque session_token and session_jwt for this session. Remember that the session_jwt will have a fixed lifetime of five minutes regardless of the underlying session duration, and will need to be refreshed over time.

This value must be a minimum of 5 and a maximum of 527040 minutes (366 days).

If a session_token or session_jwt is provided then a successful authentication will continue to extend the session this many minutes.

If the session_duration_minutes parameter is not specified, a Stytch session will be created with a 60 minute duration. If you don't want to use the Stytch session product, you can ignore the session fields in the response.

​
session_custom_claims
object

Add a custom claims map to the Session being authenticated. Claims are only created if a Session is initialized by providing a value in session_duration_minutes. Claims will be included on the Session object and in the JWT. To update a key in an existing Session, supply a new value. To delete a key, supply a null value. Custom claims made with reserved claims (iss, sub, aud, exp, nbf, iat, jti) will be ignored. Total custom claims size cannot exceed four kilobytes.

​
set_mfa_enrollment
string

Optionally sets the Member’s MFA enrollment status upon a successful authentication. If the Organization’s MFA policy is REQUIRED_FOR_ALL, this field will be ignored. If this field is not passed in, the Member’s mfa_enrolled boolean will not be affected. The options are:

enroll – sets the Member's mfa_enrolled boolean to true. The Member will be required to complete an MFA step upon subsequent logins to the Organization.

unenroll – sets the Member's mfa_enrolled boolean to false. The Member will no longer be required to complete MFA steps when logging in to the Organization.
