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 [session cookies](/docs/api-reference/b2b/frontend-sdks/vanilla-js/resources/cookies-and-session-management.md) will be minted and stored in the browser. If this method succeeds and MFA is required, the intermediate session token will be stored in the browser as a cookie. ## Parameters **code** `string` *required* The code to authenticate. **email\_address** `string` *required* The email address of the Member. **organization\_id** `string` *required* The id of the Organization to authenticate to. You may also use the `organization_slug` or `organization_external_id` here as a convenience. **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](https://stytch.com/dashboard/sdk-configuration) 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 pre-emptively 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. Parameter is an [IETF BCP 47 language tag](https://www.w3.org/International/articles/language-tags/), e.g. "en". Supported languages are English ("en"), Spanish ("es"), and Brazilian Portuguese ("pt-br"); if no value is provided, the copy defaults to English. ## Response **member\_id** `string` The unique ID of the Member. **member\_session** `object` The new Stytch Session. **properties** **member\_session\_id** `string` Globally unique UUID that identifies the Session. **member\_id** `string` Globally unique UUID that identifies a specific Member. **authentication\_factors** `array[objects]` An array of authentication factors that comprise a Session. **properties** **type** `string` The type of authentication factor. The possible values are: `email_otp`, `impersonated`, `imported`, `magic_link`, `oauth`, `otp`, `password`, `recovery_codes`, `sso`, `trusted_auth_token`, or `totp`. **delivery\_method** `string` The method that was used to deliver the authentication factor. The possible values depend on the type: * `email_otp`: Only `email`. * `impersonated`: Only `impersonation`. * `imported`: Only `imported_auth0`. * `magic_link`: Only `email`. * `oauth`: `oauth_google`, `oauth_microsoft`, `oauth_hubspot`, `oauth_slack`, or `oauth_github`. You may see an 'exchange' delivery method when a non-email-verifying OAuth factor originally authenticated in one organization is exchanged for a factor in another organization. This can happen during authentication flows such as [session exchange](/docs/api-reference/b2b/api/sessions/exchange-session.md). The non-email-verifying OAuth providers are Hubspot, Slack, and Github. Google is also considered non-email-verifying when the HD claim is empty. The possible exchange values are `oauth_exchange_google`, `oauth_exchange_hubspot`, `oauth_exchange_slack`, or `oauth_exchange_github`. The final possible value is `oauth_access_token_exchange`, if this factor came from an [access token exchange flow](/docs/api-reference/b2b/api/sessions/exchange-access-token.md). * `otp`: Only `sms`. * `password`: Only `knowledge`. * `recovery_codes`: Only `recovery_code`. * `sso`: `sso_saml` or `sso_oidc`. * `trusted_auth_token`: Only `trusted_token_exchange`. * `totp`: Only `authenticator_app`. **created\_at** `string` The timestamp when the factor was initially authenticated. **last\_authenticated\_at** `string` The timestamp when the factor was last authenticated. **updated\_at** `string` The timestamp when the factor was last updated. **sequence\_order** `string` Either `PRIMARY` or `SECONDARY`.

A previously active email address can be marked as retired in one of two ways: * It's replaced with a new primary email address during an explicit Member update. * A new email address is surfaced by an OAuth, SAML or OIDC provider. In this case the new email address becomes the Member's primary email address and the old primary email address is retired. A retired email address cannot be used by other Members in the same Organization. However, unlinking retired email addresses allows them to be subsequently re-used by other Organization Members. Retired email addresses can be unlinked using the [Unlink Retired Email endpoint](/docs/api-reference/b2b/api/members/unlink-retired-email.md). **properties** **email\_id** `string` The globally unique UUID of a Member's email. **email\_address** `string` The email address of the Member. **trusted\_metadata** `object` An arbitrary JSON object for storing application-specific data or identity-provider-specific data. **untrusted\_metadata** `object` An arbitrary JSON object of application-specific data.

A role assignment can come from multiple sources - for example, the Role could be both explicitly assigned and implicitly granted from the Member's email domain. **sources properties** **type** `string` The type of role assignment. The possible values are: * `direct_assignment` – an explicitly assigned Role. Directly assigned roles can be updated by passing in the roles argument to the Update Member endpoint. * `email_assignment` – an implicit Role granted by the Member's email domain, regardless of their login method. Email implicit role assignments can be updated by passing in the `rbac_email_implicit_role_assignments` argument to the Update Organization endpoint. * `sso_connection` – an implicit Role granted by the Member's SSO connection. This is currently only available for SAML connections and not for OIDC. If the Member has a SAML Member registration with the given connection, this role assignment will appear in the list. However, for authorization check purposes (in sessions authenticate or in any endpoint that enforces RBAC with session headers), the Member will only be granted the Role if their session contains an authentication factor with the specified SAML connection. SAML connection implicit role assignments can be updated by passing in the `saml_connection_implicit_role_assignments` argument to the Update SAML connection endpoint. * `sso_connection_group` – an implicit Role granted by the Member's SSO connection and group. This is currently only available for SAML connections and not for OIDC. If the Member has a SAML Member registration with the given connection, and belongs to a specific group within the IdP, this role assignment will appear in the list. However, for authorization check purposes (in sessions authenticate or in any endpoint that enforces RBAC with session headers), the Member will only be granted the role if their session contains an authentication factor with the specified SAML connection. * `scim_connection_group` – an implicit Role granted by the Member's SCIM connection and group. If the Member has a SCIM Member registration with the given connection, and belongs to a specific group within the IdP, this role assignment will appear in the list. SCIM group implicit role assignments can be updated by passing in the `scim_group_implicit_role_assignments` argument to the Update SCIM connection endpoint. **details** `object` An object containing additional metadata about the source assignment. The fields will vary depending on the role assignment type as follows: * `direct_assignment` – no additional details. * `email_assignment` – will contain the email domain that granted the assignment. * `sso_connection` – will contain the `connection_id` of the SAML connection that granted the assignment. * `sso_connection_group` – will contain the `connection_id` of the SAML connection and the name of the group that granted the assignment. * `scim_connection_group` – will contain the `connection_id` of the SAML connection and the `group_id` that granted the assignment. **is\_admin** `boolean` Whether or not the Member has the `stytch_admin` Role.
