You can edit the email address registered on your account by logging in online. Once logged in, you will need to head to ‘my stuff’ > ‘my account’ > ‘about me’.
To update your registered email address, you will be prompted to verify your identity via SMS or the email already registered on your account (you will have the option to choose between the two). You will then receive a 6-digit code that will expire in 10 minutes.
Once you have entered the 6-digit code, another code will be sent to your new email address. Like the first code, you will be prompted to enter this as the final step for updating your email address.
