Hi,
Thanks for the inquiry.
To change or update your Roku account email address, go to my.roku.com and sign into your account. Under the Account Information section, press the Update button and after making the changes, select Save Changes. For more information regarding updating your email address, visit our Support page here: How do I change the email address or password for my Roku account?
Please also be aware that if you would like, you can link multiple devices to the same Roku account. For more information on linking multiple devices on an account, visit our Support page here: Do I need a separate Roku account for each of my Roku® streaming devices?
Thanks,
Danny
