local authentication is considered optimal.

7.4.2 Warnings
The built-in admin account cannot be deleted.
The no username admin command does not remove the admin user, it resets his configuration to
defaults. After applying this command, the admin user will not appear in the configuration.
The no password command for the admin user also does not remove the admin user's password, but
resets it to its default value. After applying this command, the admin user password is no longer
displayed in the configuration and becomes 'password'.
User with privilege level 15 or an ENABLE password must be configured before setting the admin user to
downgrade privileges.
