Once you’ve added CBS All Access to your SHOWTIME subscription, you will need to link your SHOWTIME username and password with your CBS username and password. To do so, go to www.cbs.com/showtime or click the 'Activate Now' button upon signup. Create a new CBS account or enter your existing CBS.com credentials and follow the instructions to link your CBS and SHOWTIME accounts.
How do I activate my CBS All Access account after I add CBS All Access to my SHOWTIME subscription?
