Remove a passkey
DELETE /fapi/v1/me/passkeys/{authenticator_id} · called from the environment's sign-in host
Removes a passkey record. The removal is rejected if it would prevent the user from signing into any application in the environment. After successful removal, a security notification is sent to the user's verified email addresses (according to the environment's security notification setting). 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).
