Set up accounts for other content providers on Apple TV
Some apps and content providers, such as Netflix and HBO Max, require that you sign in before using them. When you open the app to sign in or to set up an account, follow the onscreen instructions.
Tip: You can speak usernames and passwords. With the text entry field highlighted on screen, press and hold the Siri button on the remote, then speak letters, numbers and symbols instead of using the onscreen keyboard. Say “uppercase” to indicate an uppercase letter. For more information, see Use Siri dictation on Apple TV.
