# Revoke/Suspend

Revoking certificates means blacklisting certificates permanently. Revoking a certificate invalidates it as a trusted security credential before its original validity period expires. There are several reasons why a certificate can become untrustworthy as a security credential before its scheduled expiration. Only an officer has the right to revoke a certificate.

Click on Manage user Certificate ->Revoke/Suspend from the sub-menu as shown in the below figure.
