"Hidden" means different things depending on who you're hiding from. A photo that's out of sight in the grid is not the same as a photo nobody else can open. Below are the main options, from weakest to strongest, with an honest note on what each one stops.
1. Archive it in a shared album you don't share
Some people move photos into an album with a boring name. It takes seconds, and it stops nobody who scrolls through Albums. It's fine for decluttering, but it isn't privacy.
2. Use the Hidden album
Select the photos, tap the ⋯ menu, and choose Hide. They disappear from Library, Memories, and widgets and move to Albums → Utilities → Hidden, which is locked with Face ID or your passcode.
Stops: someone glancing at your camera roll or a photo popping up in a widget. Doesn't stop: anyone who knows your passcode. The photos also still sync to every device on your iCloud account.
3. Put them in a locked note
In Notes, create a note, add the images, then tap ⋯ → Lock. You can choose a separate Notes password instead of your device passcode. Locked notes are end-to-end encrypted.
Stops: people who know your phone passcode (if you set a separate password). Doesn't stop: much, really. It's good protection, but it gets slow and awkward beyond a handful of images. See Is a locked note safe enough?.
4. Use an encrypted vault app
A proper vault encrypts each file with a key derived from a secret that's separate from your phone's passcode. Look for one that:
- explains its encryption in writing, not just "military-grade,"
- doesn't need an account or email,
- can't reset your password for you, because a vault that can reset it can also open it.
Stops: people who know your passcode, people who get your phone unlocked, and people who copy your backups. Doesn't stop: someone watching you unlock it, or spyware running while the vault is open.
Which should you use?
| You're hiding from | Good enough |
|---|---|
| Someone glancing at your screen | Hidden album |
| Your photos showing up in Memories | Hidden album |
| A family member who knows your passcode | Encrypted vault |
| Someone who might pressure you to unlock | Vault with deniable vaults |
Don't forget the leftovers
Whichever method you use, check Recently Deleted, your iCloud Photos on other devices, and messaging apps where the photo was sent or received. A photo moved into a vault is only private if no other copy is left behind.
