The account you have now is a facebook account. You'd need to create a Chess.com account if you only wanted to log in via this site, and we can transfer your premium membership over to that.
Alternatively, if you wanted to keep any of the current games you have now, you have the option of merging the Chess.com and facebook accounts.
Please note that this merges the accounts together to become one, and you can use either the facebook chess app or Chess.com login to access those games, but it doesn't merge friends lists or private messages.
If you want a password and email address adding to the facebook account, can you message those to me privately please and i'll update them for you.
I have always logged into chess.com through FB in the past. I would prefer to skip that process now and log in directly through this web site in the future. Unfortunately, I can't understand how to set up a password or email address though. I don't have a password yet on this site because I come in through FB, but I can't change my password or set up an email address without an old password. How do I go about setting up a password when I never had an original chess.com password to begin with?
