I can't connect to Apple TV with iCloud

Hello PaulMonu90,

Thank you for reaching out to Apple Support Communities, and we'll be happy to help in any way we can. We understand you're having issues with logging in with your Apple ID due to an incorrect username or password. If it is the incorrect Apple ID, or forgotten the one you use, follow the steps here to recover it: If you forgot your Apple ID - Apple Support

This article goes over several ways that you can have your password reset if the password is incorrect or you've forgotten it: If you forgot your Apple ID password - Apple Support

If after taking these steps you're still unable to reset your password, you'll need to request account recovery as described here: How to use account recovery when you can’t reset your Apple ID password - Apple Support

When completing account recovery, please make sure to power down all devices that are signed in with this Apple ID, besides the one being used to complete the request, to assist with quicker handling as using other devices with this account during the recovery process could cause your request to become cancelled.

If you run into any more trouble, or have other questions about resetting your Apple ID password, please reach out to the Apple ID team here: Get Support

We hope this helps.

Cheers!
