I run a gaming community and currently use the Steam login system which links forum accounts to Steam accounts, but the default signup method is still available.
I would like to know, if possible, how to disable the default signup method and only allow users to signup via the Steam login feature. However, the default login method should still be available to allow users to login with their username and/or email address once they've actually signed up.
Furthermore, is there a possibility to "sync" user data between the forum and the Steam servers if, for example, users change their Steam name or profile picture etc.
Thanks in advance!
