Sorry, you're going to need a Gmail account.
You cannot log into Google Page Creator using your Google Account username and password.
Google Page Creator is in a limited test period and is currently available only to Gmail users. If you have a Gmail account, please try to log in again using your Gmail username and password.
If you don't have a Gmail account, you can sign up for one using your mobile phone. Then, come back and check out Google Page Creator!
