Go to the official site at Peacocktv, and click on the log-in button shown on the upper right-hand side of the screen. You will see a pop-up box with a prompt for you to enter your account information and log in to the site from here.
From the new screen, you’ll see any profiles that are associated with your Peacock account. While you can click those to access the site, if you select the Account button with the gear icon, you’ll be taken to Account Settings.
When you have the account screen open, you’ll see three tabs for Plans & Payment, Settings, and Devices. If the Plans & Payment tab isn’t already open, select that to pull up your subscription. This will show your current subscription, and how you signed up for the service.
When you click on Manage, you’ll be taken to a new screen or pop-up giving you the option to proceed. Follow the prompts and confirm as needed until your subscription is canceled. If successful, you should see a similar screen to the one below.
