I've no idea what the alias method is! I was advised to use a private browser, but same thing happens. In checking over some other topics I see many people have had trouble porting and accessing their account. Could be a PM problem?
This may or may not be the issue, @jsr2125 , however if you're logging in from a mobile device with stored/remembered credentials which auto-fill, let them auto-fill, then the system will try to log you in automatically once they auto-fill.
If your system does this, DO NOT tap the log in button as it'll deliver an error message every time and not allow account access.
