While you can lock individual notes in Apple Notes, you cannot natively lock an entire folder with a password. However, there is a workaround to protect multiple notes at once.
How to Protect Notes
- Apple Notes requires you to lock notes individually.
- Open the note you want to protect.
- Tap the three dots in the top right corner.
- Tap Lock. You can choose to use your iPhone passcode or create a separate password.
- Repeat this for all sensitive notes in the folder. A lock icon will appear next to them.
