Register and log in with just a license. Once the license is used for the first time, users will only need to use the license to access the application.In order for this to work properly, the license must be unused. After using it for the first time it will "register" the user, and then turn the license into a user (you will be able to see it on the users page of the website). Every time after you attempt to log in, it will just log in normally.
