If a user forgets the login password of the Roku account login account, he can reset it using the web interface of the Roku device. To reset the login password, you need to know the email address registered to the Roku account. When the reset password process gets done, a password recovery mail will get sent to your registered account. Click on the activation link that you received in your mail and follow the rest of the instructions to reset the password. The link sent to you will only be valid for an hour.
