Once you have activated your PBS Passport account, you can follow the steps below to sign in with your Passport account on your Amazon Fire TV.
Open the PBS app on your device.
In the left navigation, scroll down and select Profile.
In the Profile menu, select the Change Account option.
Confirm that you would like to Log Out of the account on your app. This will deactivate the app.
The PBS app will ask you to activate the app. Select Activate Now.
Activation instructions appear on the screen along with a 7-character activation code. You'll need this code for the next step.
Go to your computer and open a web browser to visit pbs.org/activate
Enter your device's unique activation code in the "Activation Code" field. Click Continue.
You are taken to a new page asking you to sign in with a Google, Facebook, or PBS account.
Choose the same account you used when you activated Passport. If you sign in with a different email address, you will not be signed in with your Passport account and will be unable to watch Passport videos.
After signing in, your device has been activated.
Your device will automatically update. If you signed in with the same account you linked to your Passport benefit, you can now access Passport videos on your device.
