Using the Siri remote to enter text on an Apple TV is difficult, especially when the sentence is long and complicated. Instead, you can use the software keyboard on your iPhone or iPad to enter your password.
This feature has been added again in iOS 12. Apple's tight ecosystem makes sense here, and we are taking full advantage of it. The Siri remote is not great, and entering a 12-character password with symbols, capital letters and numbers is delusional. This feature is not just about passwords, whether you're looking for your favorite movie or capturing the best password in the world, using an iPhone or iPad keyboard is a much better idea.
How to use an iPhone or iPad to enter text
For this to work, you will need an iPhone or iPad running iOS 12 or later and an Apple TV under tvOS 12 or later. All devices must be on the same Wi-Fi network and connected to the same iCloud account.
Access a text field on your Apple TV and you will receive a notification on your iPhone or iPad inviting you to open the keyboard. If the notification does not appear, you can also open the Apple TV Remote Application (if you have never used the Apple TV remote, Discover this guide to put everything in place). A keyboard will appear automatically when your Apple TV is ready for text input.
Use the keyboard as usual and enter your text.
Anything you type will automatically appear on your Apple TV in real time. Continue with the Siri remote control of your Apple TV once you are done.
How to use automatic filling
Being able to enter text using the keyboard of your iPhone or iPad also gives you access to Automatic filling. Auto-entry allows you to quickly and easily enter passwords without entering anything if your usernames and passwords are saved in iCloud Keychain or in an application such as 1Password or Last passage.
To use AutoFill, tap the credentials when they appear in the QuickType bar above the keyboard of your iPhone or iPad. If you have more than one identifying information, press the key icon and select the correct one.
The user name and password will be automatically sent to your Apple TV after your authentication via Touch ID or Face ID. It never appears in plain text on your iPhone, iPad or Apple TV.
This is just a tip for your Apple TV to work for you. There is much more that you can not know. If you do not have elastic at the bottom of your Siri remote, you miss the challenge!
