# Unlink an identity

`DELETE /fapi/v1/me/identities/{identity_id}` · called from the environment's sign-in host

Unlinks a social or enterprise identity from the authenticated user's account. The user's last login method cannot be removed. If the user's organization enforces SSO on this link, the identity can only be removed via the customer management API. After successful removal, a security notification is sent to all of the user's verified email addresses. Requires the authenticated user's `__Host-idp_session` cookie; if the cookie is missing, expired, or revoked, returns `401 unauthenticated`. A first-party app on another origin can instead send its front API access token (`Authorization: DPoP <token>` with a DPoP proof; see [Front API access token](/docs/api/fapi/front-api-token)).

The session must have been verified in the last 5 minutes. If the user has a second factor, the session must also have been opened with a second factor (`urn:idp:acr:mfa`).
