How to password protect photos on iPhone

People often search for a way to put a password on one photo, the way you might on a PDF. iOS does not offer that. What it offers are a few nearby features, and which one works for you depends on what you mean by “password” and who you are protecting the photo from.

Why there is no per-photo password

The iPhone’s security model protects the whole device with one passcode. When the phone is locked, your data is encrypted; once you unlock it, apps you open can show their contents. Individual photos do not carry their own locks. The Photos app adds a second prompt only for two system albums, Hidden and Recently Deleted, and that prompt uses the same Face ID, Touch ID or passcode as the lock screen.

So there are really two separate needs hiding behind the question:

1. “I don’t want it in my camera roll.” That is a visibility problem, and hiding solves it.
2. “I want it to need a secret only I know.” That is an access problem, and it needs a lock that is different from your device passcode.

Option 1: hide it behind Face ID

If your main concern is someone scrolling past the photo, hiding it is quick:

1. Open the photo in Photos.
2. Tap More (•••) › Hide.
3. Check that Use Face ID is on in Settings › Apps › Photos (Settings › Photos before iOS 18).

The photo now sits in the Hidden album, behind biometric authentication. It is not a password in the usual sense: anyone who knows your iPhone passcode can choose the passcode fallback and open the album. More detail is in how to hide photos on iPhone.

Option 2: a locked note with its own password

Apple Notes is the only built-in app that lets you set a separate password, distinct from the device passcode, for content you choose. A locked note is encrypted, and attached photos are included.

1. Go to Settings › Apps › Notes › Password (Settings › Notes › Password on older versions) and choose to use a custom password rather than your iPhone passcode. Add a hint you will understand and others will not.
2. In Notes, create a new note. Tap the camera button and either take a photo directly into the note or choose one from your library.
3. Tap More (•••) › Lock.
4. Return to Photos and delete the original, then delete it again from Recently Deleted.

Taking the photo directly inside the note is the cleaner path, because it never lands in your camera roll in the first place.

Be aware of the trade-offs. Notes syncs through iCloud if you use iCloud for Notes, and Notes is not designed for viewing many photos or videos. If you forget the custom password, those notes cannot be opened. Velcrypt vs Apple Notes locked notes goes into the comparison.

Option 3: an encrypted vault app

A photo vault is an app that keeps its own encrypted copy of your images, locked with a secret the app manages. This is the closest thing to a real per-photo password: you decide exactly which photos go in, and the device passcode does not open them.

Look for a few things before trusting one:

• Real encryption, not just a hidden folder. The app should encrypt files on the device with a modern authenticated cipher.
• A lock independent of the device. If the vault opens with Face ID alone, it inherits the same passcode fallback problem as the Hidden album.
• Clear data handling. Does it upload to a server? Does it need an account? What happens if you forget the code?

Comparing the options

	Hide	Locked note	Vault app
Separate from device passcode	No	Yes, with a custom Notes password	Usually
Removes photo from camera roll	Yes, moves it to Hidden	Only if you delete the original	Only if you delete the original
Comfortable for many photos	Yes	No	Yes
Handles videos well	Yes	Poorly	Usually
Built into iOS	Yes	Yes	No

Choosing a secret worth having

A separate password only helps if it is genuinely separate. A few habits make the difference:

• Don’t reuse your iPhone passcode. If the people you are protecting against know your passcode, a matching Notes password or vault code gives them both.
• Avoid the obvious. Birthdays, anniversaries, 1234-style sequences and the same code as your banking app are the first things anyone tries.
• Make it memorable to you alone. You will not be able to reset it in most cases, so pick something you can recall months from now without writing it on a sticky note in your phone case.
• Mind your surroundings. Any secret can be read over your shoulder. Enter it when nobody is watching the screen.

A note on the originals

Whichever lock you choose, a protected copy does not help if an unprotected copy is still around. After moving a photo into a note or vault, delete it from Photos, empty it from Recently Deleted, and think about other places it might exist: an iCloud shared album, a chat thread, a cloud storage app. The guide to deleting originals after import walks through each step.

Where Velcrypt fits

Velcrypt answers the second need, a secret only you know. Instead of a typed password, you draw a pattern on a 5×5 grid of dots. It has to pass through at least six dots with at least one change of direction, and patterns of eight to twelve dots are recommended. Velcrypt does not use Face ID or Touch ID at all, so your iPhone passcode and your face cannot open it.

Each pattern opens its own vault, and the photos inside are encrypted with AES-256-GCM using keys derived from that pattern. Because everything stays on the device and is excluded from backups, there is no way to reset a forgotten pattern. If you would rather have a password you can recover, that limitation is worth weighing honestly before you move anything important.
