You can log in to the Classmates site from any computer or mobile device - you'll just need your password and either your registration number or the email address associated with your membership.
To log in, enter your email address and password on the main page of Classmates.com and select Log In. You can also choose to log in using your Facebook account.
If you're sharing a computer, you might see a message that someone else is logged in. You'll need to log that person out first by clicking Sign Out under the gear 
icon in the orange bar at the top of any page. Choose a sign out option and then sign in to your own account.
If you've forgotten or misplaced your password, click Forgot? on the login page and follow the prompts. We'll send you an email with a link to reset your password.
