If you’re like most people, you take a lot of notes on your iPhone. Whether you’re taking quick ideas for a presentation or jotting down grocery lists, your iPhone is the perfect place to store your thoughts. But what if someone else gets their hands on your iPhone? There are a few things you can do to protect your notes:

  1. Lock Your Notes: One of the simplest ways to protect your notes is to lock them away. To do this, go to Settings and then tap on “Lock Screen”. From here, you can set a passcode for your notes or choose to have them automatically locked after a certain amount of time has passed.
  2. encrypt Your Notes: If locking your notes isn’t enough security for you, you can also encrypt them using Apple’s FileVault feature. This will make it so that no one else can access the notes unless they have the correct password.
  3. Backup Your Notes: Another way to protect yourself is by backing up your notes regularly using iTunes or iCloud backup services. This way, if something happens and your phone is lost or stolen, at least some of your information will be safe and sound. ..

If you tend to jot down sensitive information in the Notes app on your iPhone or iPad, you may want to keep them protected behind a password. Here’s how to enable the feature in iOS 11.

Granted, your device is likely already locked down with a passcode. So anyone looking to gain sensitive information on your phone still has to get past the main gate. However, multiple checkpoints are always good for security, so password-protecting certain notes is still worth doing. In the Notes app on iOS, you can even choose which notes to lock down.

To get started, open up the Notes app on your iPhone and swipe to the left on a specific note that you want to lock down. In this case, I’m going to put a password on this note containing the serial numbers to some of my devices.

This will bring up several options, but you’ll want to tap on the gray lock icon.

You’ll be taken to another screen, where you’ll enter in a password that will be used to unlock all and any notes that you want to password-protect. Enter in a password (and verify it by entering it in again) and then hit “Done” in the top-right corner.

You’ll be taken back to the Notes app, where you’ll now see a padlock appear next to the note. It will start off in an unlocked state.

To lock the note, tap on “Lock Now” at the very bottom of the screen.

The note will now be locked and all of the preview text that you were able to see earlier will be gone and replaced with either “Locked” or “Unlocked”.

When you go to open up a note that is locked, tap on “View Note”.

If you have Touch ID, you can simply use that to unlock the note, but you’ll also have the option of typing in the password.

After that, you’ll have access to your note. Once you’re done with it, you can tap on the unlocked padlock icon in the upper-right corner of the screen to lock it back up.

You can also go back to the main screen of the Notes app and tap on “Lock Now” at the bottom (like you did before) to lock all unlocked notes at once.

To remove password protection entirely from a note, swipe on it like before and tap on the gray lock icon again.

You’ll be asked to use Touch ID or enter in the password to verify (just like if you were unlocking a note to view it), but after that the note will now be completely unlocked for good.

Keep in mind that if you sync notes across your various Apple devices using iCloud, locking a note will also lock it on your other devices, and vice versa.
