If you're not sure why the ability to lock notes with Face ID on iPhone is incredibly useful, allow me to explain. 

Before Apple launched iOS 16, you could lock notes in the iPhone's Notes app. You'd tap the lock button and set a password and all would be well — your note would be secure, your top secret plans just that. The problem was, though, that this password was separate to your iPhone unlock passcode and could be anything you like. As a result, issues arose if you ever forgot the password to that specific note. And let me tell you from first hand experience that this was an all-too-common situation, especially when digging out and trying to unlock a note from 3 years and three iPhones ago. 

Now, thanks to iOS 16, iPhone users can lock notes using their main unlock passcode and/or Face ID. This is similar to how notes have been lockable and unlockable on Mac using a thumbprint/Apple ID. It's super useful and means you don't have to stress about remembering yet another password, so your embarrassing poetry can stay private.

Note: Moving to Face ID/passcode locking affects all locked notes on your iPhone, meaning the steps below are required only once and you don't need to repeat the process to lock individual notes with Face ID/passcode. 

How to lock notes with Face ID on iPhone

1. Open the Notes app and select a note without a lock, or create a new note. In the top right corner, tap the three dots icon.

4. If you have multiple Apple devices which aren't compatible with these changes, you'll receive a warning telling you which devices your passcode locked notes will not be available on. Make a note of these and then tap continue.

5. You'll receive a prompt to tell you that your Locked Notes have been updated to your Device Passcode. Tap OK.

That's all there is to it. You now needn't worry about losing or forgetting your notes passwords. You can still view your top secret recipe ideas without ever risking them being seen or stolen.
