If you’ve created an account using Google login, but haven’t set a password, you won’t be able to change your email until you choose a password.

If you can’t change the password because there’s already an account associated with the new email, log out and log in with the new email. If you’re not sure what’s the password, click on the Forgot password on the log-in page.
