My AppleTV is not working
When I put in my password that I know of you it’s wrong how do I change it?
1080p,
On what device with the Apple TV app is this happening?
If you don’t remember the correct password: If you forgot your Apple ID password - Apple Support
If you do know the correct password, but it still gives you sign-in errors, then contact Apple Support.
Also consider if the Apple ID account name (email address) was spelled correctly.
