AuthMe can be configured to have optional registration. Players can choose if they want to register or not. However this allows any player who joins with the same name as a staff member to have the staff member's permissions. To prevent any player to execute the Staff++ commands we have integrated the AuthMe plugin. Configure the authentication provider inside the Staff++ config to "authme". This will make sure any player who tries to execute a Staff++ command must be logged in and have the correct permissions. In other words we enforce authentication before you can use Staff++ commands even if AuthMe registration is optional.
