No problem! You can still sign in using your old email address. Once you've logged in with your old email, you can change your email address by clicking "edit email or password". This can be found in the top right corner in the drop down menu under your name.
On the account settings page, you will be able to change your email address and other basic information such as your name, gender and birthday.
If you no longer remember the password to your CrossFit ID account or are having other issues logging in with your old email address, please contact Games Support at email@example.com to update your email address. They can update the email address for you.
Logging in with your old email address is well worth the effort. By signing in using your old account name, all of your past performances and statistics will be present on your profile.
