To change the email on your Roku TV, access the account settings through the device menu. First, press the Home button on your Roku remote to open the main menu. Navigate to Settings (usually found at the top or bottom of the menu), then select Account or User & Account. Look for an option labeled Email address, Roku account, or Manage account. Select it and choose Change email or a similar option. You'll be prompted to enter your current Roku account password for verification, then enter your new email address. Confirm the change by following any additional on-screen prompts. After updating, check your new email inbox for a verification message from Roku—click the verification link to complete the process. If you've forgotten your password, select the "Can't sign in?" option on the account screen to reset it via your current email before making changes. Alternatively, you can manage your Roku account email through the Roku mobile app or the Roku website (roku.com) by logging in and visiting Account Settings, which sometimes offers a more straightforward interface. The exact menu labels may vary slightly depending on your Roku model and software version, but the general pathway through Settings and Account remains consistent across most Roku devices.
