iPhone Notes lock vs an encrypted vault
Locked Notes are fine for short text secrets with a generic first line and a separate Notes password. For scans, photos, PDFs, and anything you do not want inside Notes, use an encrypted vault like Blopman.
What Notes lock does well
Apple encrypts locked note bodies. That is stronger than a fake “hide” toggle.
Gaps to remember
- The first line remains visible as the title
- Passcode-locked notes open with the same Face ID/passcode as the phone
- Many attachment types cannot be locked
Simple rule
Sentences → locked Notes (maybe). Files and photos → vault.
FAQ
Are locked Notes encrypted?
Yes, the body is. The title visibility and shared passcode are the practical weak spots.
