If you store valuable information in Apple Notes, you need to read this.

The Apple Notes app has an important feature that many users overlook, but it’s arguably the most important thing you should use for all your notes synced across iOS, iPadOS, macOS, and iCloud.com. And Apple’s latest updates make it much easier to use than before, so there’s no reason why you shouldn’t use it.

How Apple Protects Your Notes

If you sync the Notes app with iCloud, all your notes will be protected with your device passcodes and passwords, and you’ll be able to unlock your devices much faster with Face ID or Touch ID. When you access them from iCloud.com, you need your Apple ID password to see them. Pretty safe, right?

Apple updates for iOS 16.2, iPadOS 16.2, and macOS Ventura 13.1 provide enhanced security with Advanced Data Protection for iCloud. When enabled, all your notes are end-to-end encrypted via iCloud and you can only access your notes on trusted devices. You can even turn off access to notes on iCloud.com for more protection, but it’s not required.

Why you should add even more protection

Even with all this security, people can access your notes. For example, if you’re working on your Mac and your notes are visible, anyone nearby can view them if you step back for a minute without leaving the lock screen. This can happen at work, at school, or even in your home. While it’s unlikely you’ll leave your iPhone lying around, your iPad may be a different story.

To protect your notes in such cases, you should lock the Notes app. While you can technically lock the entire app itself, it’s best to lock each note with a passcode and Face ID or Touch ID if you plan on syncing notes between iCloud-connected devices.

Password-protected notes and optional Touch ID unlock have been available since iOS 9.3 and Mac OS X El Capitan 10.11.4, with Face ID support coming later. If you want maximum security, you can even choose different passwords for each note instead of one for all. But either one makes the possibility of blocking your own notes much higher if you don’t have a secure way to write them down.

Apple’s iOS 16, iPadOS 16, and macOS Ventura 13 make it easier to use secure notes by allowing you to lock notes with your device’s passcode or password, rather than a Notes-specific one. If you use a strong password for your devices, it will be almost impossible to hack them.
