Using certificates over the standard username and password credentials have certain benefits as the certificates provide stronger authentication against unauthorized access. It also eliminates the need for end users to enter in a password or renew one every month. Sensitive emails between recipients can be encrypted through S/MIME or prove your identity through a message signature.
