Supplement called SimpleAuthHelper that is placed on top of the authorization
SimpleAuth plugin and allows you to remove the need of typing the commands /register and /login, now players only need to enter the password with the command /123456, this makes the process of registration and authorization is much easier.
To increase the security level, as when registering on the server with this plugin, the password must be entered twice, that will get rid of the situations when the player entered a password by mistake and can't login again.
