Forgot your photo vault PIN? What you can do on Android
How PIN recovery works in photo vault apps, why some vaults can’t recover at all, and what to try first when you’re locked out of yours.

Forgetting a vault PIN feels like losing every photo inside. Whether you can get back in depends on how your vault handles recovery, and its makers decided that long before you forgot anything. Here is how the common approaches work, what to try first if you forgot your photo vault PIN, and how to make sure it never becomes a problem.
First, stop guessing
Wrong guesses can make things worse. Many vaults make you wait longer after each wrong PIN, and some can erase themselves after a set number of tries. That feature exists to stop intruders, and it works just as well against a forgetful owner. Before you try again:
- Write down the PINs you might have used, then try them calmly, one at a time.
- Think about the PINs you use elsewhere and the length you usually choose.
- If your vault warns that it will erase itself after a few more tries, stop and look for a recovery option instead.
How vaults recover a forgotten PIN
Every way of recovering a PIN is a trade-off between letting you back in and keeping everyone else out.
| Recovery method | How it works | The catch |
|---|---|---|
| Email or account reset | The vault sends a reset to an email address or account | Anyone who can get into that email or account may be able to reset it too |
| Security question | You answer a question you chose earlier | Answers are often easy to guess or find online |
| Recovery key | You saved a long key when you set up the vault | Lose the key and this option is gone |
| No recovery | Nothing can reset the PIN | A forgotten PIN means the files can't be opened |
A vault with no recovery isn't necessarily badly made. If the files are properly encrypted and only your PIN unlocks them, nobody can let you back in, including the company that made the app. That's exactly what protects you if someone else gets your phone, and it's why a backup or a recovery key matters so much.
Be wary of "vault unlock" tools
Search for help and you'll find tools and services that promise to crack vault apps or pull out their photos. Treat them with suspicion. A vault that only hid your files might be opened that way, but one that encrypts them properly can't be opened without the key, and paying a stranger to try puts your private photos in their hands.
Make sure it never happens
- Set up recovery on day one. Whatever your vault offers, a recovery key, an account reset or a backup, turn it on when you set up the vault, not when you need it.
- Store the recovery key properly. A password manager or a paper copy somewhere safe works. A screenshot in your gallery doesn't, because it's the first place a snooper would look.
- Choose a PIN you'll remember. Something long you can recall beats something clever you'll forget. Avoid your phone's unlock PIN, birthdays and repeated digits.
- Keep a backup. If the worst happens, a backup you can restore with a new PIN brings your files back.
If you're locked out of Hidey
Hidey offers different ways back depending on how you set it up:
- You back up to Google Drive. On the lock screen, tap forgot pin to reset it with Google. For your safety there's a 24-hour wait, timed by Google's servers rather than your phone. If you remember your PIN in the meantime and unlock, the reset is cancelled, and Hidey shows you that someone asked for one. The trade-off: whoever controls your Google account could do the same, which is why zero-knowledge mode exists.
- You set up a recovery key (zero-knowledge mode, Pro). There's no Google reset in this mode. Enter the recovery key you saved when you turned it on: 28 characters in groups of four.
- You use fingerprint unlock. Your fingerprint still opens the vault, so you can unhide your files or export a backup file. Changing the PIN itself always asks for the current one.
- None of these. Hidey can't reset your PIN. If you exported a backup file and kept its code, you can restore it after reinstalling Hidey, with a new PIN.
A hidden vault's PIN (Pro) can't be reset at all, so nothing can reveal the vault exists. Choose those PINs with extra care.
Wrong PINs make Hidey wait longer each time, and if you turned on self-destruct (Pro), it warns you before your last three tries. Reinstalling instead? See what happens to your photos when you uninstall a vault app. The security page explains how each option works.
