As of 9/30/2020 the iHeartRadio app for Roku no longer allows login or authentication via Facebook or Google login. This means that going forward you will need to login using the email address and password associated with your iHeartRadio account.
If you have never logged into your iHeartRadio account using an email address and password you may need to associate these credentials with your Facebook or Google login.
Under the Account section you should see the message below:
All you need to do is select Add Email and you'll be prompted to enter a password and email address to associate with your account.
If you have any trouble with this process or need further assistance, please contact our support team by hitting the Contact Us button below.
