# Revoking Mobile Credentials

> Learn how to delete mobile credentials.

To revoke a mobile credential, [delete the credential](/low-level-apis/access-systems/managing-credentials#delete-a-credential). Seam issues a discard command for the Visionline card. If you are deleting a [multi-phone sync credential](/capability-guides/mobile-access/issuing-mobile-credentials-from-an-access-control-system#what-are-multi-phone-sync-credentials), Seam discards all of the credentials that were created underneath it.
