If you've activated Netflix on your Fiber TV Box, you can deactivate it to sign out of your Netflix account at any time. For example, if you change your Netflix password or want to sign in with a different account, you can deactivate Netflix, and then activate the service again with the new account information.
You need to deactivate Netflix on each Fiber TV Box from which you want to sign out of the Netflix app.
To deactivate Netflix on your Fiber TV Box:
Press on the remote control, select Settings, and press ok.
Select Advanced and press ok.
Select Deactivate Netflix and press ok.
In the confirmation message, select OK and press ok.
