Yes I understand why you’d wonder that. Basically the login is handled by SMS with the mobile number, the username is just being created in a way that the client wants to see it in the admin table.
In other words the user isn’t logging on with the username. The username just needs to be a country code, a underscore and the login which is the $login.
There may be a better way to do that, but at the moment I just wanted to see if i could do it this way, witha filter.
Thanks
