Player can't log in

I have two players who are getting an error that says Invalid Login credentials. I’ve created a new player account to see if it was a problem with the account but they can’t seem to log into this either while i was able to. Any ideas on what might be causing such an issue?

Are they trying to log into the game or log into The Forge? Some users seem to get confused at first and try to login into The Forge with the Foundry player credentials their DM created for them.

Yes, turns out they were logging into the wrong site.
