You can sign up for the free 24 Hour Pass on our website. When you try to access unlocked content, you can choose "Start a 24-hour pass" instead of signing in to a TV provider.  You will enter your email address, a password, and your birth date to register the one-time use pass. Be sure to note the password you created, as it cannot be reset.
 
If you experience playback issues or need to sign out, clear the browser cache and sign in again.

There is no way to reset the password, cancel the pass, or reset the pass if it stops working. It will expire automatically.
