Much of my time has been wasted trying to figure out how to change Amazon accounts from the Roku app. So I thought I’d write this post up to save others the trip. It would be wonderful to add multiple accounts, but the app only allows you to use one account at a time. If you want to switch accounts, the only way is to unregister the device. Here’s how.
1. Open the Amazon Instant Video app.
2. Choose the “Help & Settings” option.
3. Select “Unregister Device”.
4. Select “Unregister”.
5. Press “Home”.
6. Open the Amazon Instant Video app again. You will be prompted to login. Use the credentials for the Amazon account you wish to use.
Once signed in, your Roku is now ready to use with the new account.
