Multiple users on Apple TV Autonomously ?

Hello Ph1ppo,

Here's an article to help with setting up your Apple TV with your Apple ID: Set up your Apple ID on Apple TV

You're not able to sign in with both Apple IDs at the same time.

Take care!

Ph1ppo,

Try deleting the user and setting it up again. This should resolve the third party apps that are set up with your account information. Here's how to do this:

Remove a family member from Apple TV

1. Open Settings  on Apple TV.

2. Go to  Users and Accounts > [account name] and select Remove User from Apple TV.

You can also add people to your Apple TV using the Home app on an iOS, iPadOS, or macOS (running Catalina or later) device. The Home app lets you add multiple users at the same time and customize each person’s access by device. For example, you can set up an Apple TV in the kids’ room with a child account, and set up another Apple TV in the living room with both parent and child accounts. 

1. Make sure your Apple TV is added to a room on the network controlled by the Home app.

If you didn’t choose a room for your Apple TV when you set it up, open Settings  on Apple TV, go to AirPlay and HomeKit > Room, then choose a room.

2. Open the Home app on your iOS, iPadOS, or macOS device.

3. Tap  in the upper-left corner of the screen.

4. Tap Invite, enter the Apple ID email address for the user you want to add, then tap Send Invite.

5. Tell the invitee to open the Home app on their iOS, iPadOS, or macOS device and do the following:

a. Tap Accept.

b. Tap , then tap their name.

c. Tap Show Me on Apple TV, then turn on one or more Apple TVs.

The family member will now appear as a user for those Apple TVs.
