Facebook Connect securely links your Classmates account with your Facebook account, allowing you to sign in to the Classmates site using your Facebook login information—so you don't have to remember yet another password! Your profile will also be populated with fresh content, making it easier for your schoolmates to find and reconnect with you.
To link Facebook with the Classmates site, sign out of your account and then sign back in by clicking Log in with Facebook.
Note: You'll still need to use your Classmates password to access and update your personal and billing information in your Account.
