Clicking Connect with Facebook links your Classmates® account with your Facebook account, allowing you to sign in to Classmates using your Facebook login information—so you don't have to remember yet another password! Your Classmates profile will also be populated with fresh content, making it easier for your schoolmates to find your profile and reconnect with you.
If you haven't yet linked your accounts, you'll see the Connect option under the gear icon at the top of each Classmates page.
Clicking Sign in with Facebook allows you to securely sign in to your Classmates account without having to enter a Classmates password. This requires being signed in to your linked Facebook account.
If you haven't already linked your accounts, you'll see the option to do so when you click Sign in with Facebook or Connect with Facebook.
Note: You'll still need to use your Classmates password to access and update your personal and billing information in your Account, found under the gear icon at the top of every Classmates page.
