You must login with your TV subscription ID and password. If you are unsure whether you have a username/password for your TV company or you've forgotten them, you can recover both by contacting your TV provider.
Please note: You must have a TV provider that supports AMC's full episode service and you must have AMC as part of your TV package. (See the list of currently supported providers above.)
When you click to watch a full episode, you will be offered the opportunity to log in using the username/password associated with your TV account.
