B2B Passwords

Authenticate

Changed on

Authenticate an email/password combination in the discovery flow. This authenticate flow is only valid for cross-org passwords use cases, and is not tied to a specific organization.

If you have breach detection during authentication enabled in your password strength policy and the member's credentials have appeared in the HaveIBeenPwned dataset, this endpoint will return a member_reset_password error even if the member enters a correct password. We force a password reset in this case to ensure that the member is the legitimate owner of the email address and not a malicious actor abusing the compromised credentials.

If successful, this endpoint will create a new intermediate session and return a list of discovered organizations that can be session exchanged into.

Request body

email_addressstring required

The email address of the Member.

passwordstring required

The password to authenticate, reset, or set for the first time. Any UTF8 character is allowed, e.g. spaces, emojis, non-English characters, etc.

Response

Successful response

request_idstring required

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.

email_addressstring required

The email address.

intermediate_session_tokenstring required

The returned Intermediate Session Token contains a password factor associated with the Member. If this value is non-empty, the member must complete an MFA step to finish logging in to the Organization. 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. Password factors are not transferable between Organizations, so the intermediate session token is not valid for use with discovery endpoints.

status_codeinteger required

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.
