How to Hide Photos and Files on Your Smartphone
Native secure folders and hidden albums — what actually locks your files, and what just tucks them out of sight.
Before installing a third-party vault app that asks for full access to your photo library, it's worth knowing that both Android and iPhone already have built-in ways to hide and lock photos and files — some of them genuinely password-protected, and some that just move a file out of the main gallery view without securing it. The difference matters, so this guide separates real security from simple hiding, and walks through both platforms.
Hidden Isn't the Same as Locked
This is the single most important distinction in this guide: a "hidden" album on both Android and iPhone removes photos from the main gallery grid, but on many devices it doesn't require a separate password to open — anyone who knows where to look, and has access to your already-unlocked phone, can still find it. A genuinely secure folder, by contrast, requires its own PIN, pattern, or biometric check even after the phone itself is unlocked. Know which one you actually need before you pick a method.
Hiding and Locking Files on Android
1Use Google Photos' Locked FolderAndroid
Inside the Google Photos app, go to Library > Utilities > Locked Folder (naming varies slightly by app version). Photos and videos moved here require your device PIN, pattern, or biometric unlock to view — separately from unlocking your phone itself — and they're removed from your main photo grid, other apps, and shared albums entirely. This is genuine, built-in security, not just hiding.
2Set up Secure Folder on Samsung devicesAndroid
Samsung phones include Secure Folder, found in Settings or the app drawer, which creates an entirely separate, encrypted space with its own apps, photos, and files, locked behind its own authentication. It's more robust than a locked album since it isolates an entire mini-environment rather than just a folder of images, useful if you want more than photos kept separate.
3Try Private Space on newer Android versionsAndroid
Android 15 introduced a system-level Private Space feature (Settings > Security & privacy) that creates a separate profile-like area with its own PIN and its own set of apps, hidden from the main app drawer entirely until unlocked. Availability depends on your specific device and Android version, so check under Settings if this matters to you — not every phone has it yet.
4Lock a gallery app with an app lock, if your device offers one
Some Android skins include a built-in app-lock feature (often under Settings > Security or Settings > Apps) that lets you require a PIN or fingerprint before your Gallery or Files app opens at all. This adds a layer even before someone reaches a locked folder inside the app, though availability and naming vary significantly by manufacturer.
Hiding and Locking Files on iPhone
5Move photos to the Hidden albumiPhone
Select any photo, tap the share icon, and choose Hide to move it into Utilities > Hidden inside the Photos app. This removes it from your main library and Memories, but by default the Hidden album itself is only tucked away, not password-protected — check the next step to actually lock it.
6Require Face ID or a passcode to open Hidden and Recently DeletediPhone
In recent iOS versions, go to Settings > Photos and enable Require Face ID (or Touch ID/passcode, depending on your device) under the section for the Hidden and Recently Deleted albums. Once turned on, opening either album requires a separate authentication check even when the phone itself is already unlocked — this is the step that actually turns "hidden" into "locked."
7Use Notes for locked documents and scansiPhone
For scanned documents, IDs, or text you want protected rather than just a photo, the Notes app lets you lock an individual note behind Face ID or a passcode via the lock icon in the note's toolbar. It's a genuinely useful option for sensitive documents that don't need to live in your camera roll at all.
8Know the limits of the Files appiPhone
Unlike Photos, the built-in Files app on iPhone doesn't offer a native folder-level lock — anything stored there is only as protected as your phone's overall passcode. If a document needs its own separate lock, Notes (see above) or a locked folder within a third-party file-management app is the better option.
What These Methods Don't Protect Against
9Cloud backups can still contain the original
Hiding or locking a photo on your device doesn't automatically remove it from a cloud backup, and it may still be visible if you check that same account on a different, already-logged-in device or the web version of Google Photos or iCloud. Check your specific backup app's own privacy settings if this matters for a particular file.
10Anyone who knows your phone's main passcode can usually reset the rest
Most of these locks rely on the same underlying biometric or PIN system as your phone's main lock screen. If someone has your device passcode, they can typically reset or bypass an app-level lock through account recovery options — so a secure folder is protection from casual snooping on an already-unlocked phone, not a substitute for keeping your main passcode private.
Note: Menu names and exact steps vary by manufacturer (Samsung's One UI, Xiaomi's HyperOS) and by iOS/Android version. If a setting isn't exactly where this guide describes, search your Settings app using the bolded keyword from that step.
FAQ
Is a hidden album on iPhone or Android actually password-protected?
Not by default. On iPhone, you need to separately enable Face ID/passcode protection for the Hidden album under Settings > Photos. On Android, Google Photos' Locked Folder is protected by default, but a simple "hidden" gallery feature on some manufacturer skins may not be — check the specific feature you're using.
Can I hide an entire app, not just photos?
Samsung's Secure Folder and Android's newer Private Space feature can both hide entire apps behind a separate lock, not just individual photos. iOS doesn't currently offer an equivalent for hiding a full app, only individual photos, files, or notes.
Will hidden or locked photos still show up in search or Memories?
No — on both platforms, moving a photo into a hidden or locked folder removes it from search results, Memories, shared albums, and widgets, which is one of the genuine benefits over simply relying on a passcode for your whole phone.
Do I need a third-party vault app?
For most people, no. The built-in options on both platforms cover hiding, password-protecting, and isolating sensitive files without granting a third-party app access to your entire photo library. A vault app is only worth considering for very specific features neither platform offers natively.
What happens to hidden files if I factory reset or switch phones?
If they're backed up to your Google or iCloud account, they typically transfer with the rest of your data when you sign back in on a new device, though the lock status itself may need to be re-enabled after setup. Check your specific backup settings before a reset to confirm what's included.
Use a hidden album if you just want clutter out of your everyday camera roll and no one else has regular access to your unlocked phone. Use a locked folder or Secure Folder/Private Space if other people do have access to your unlocked device and you need a genuine second layer of authentication. Skip a third-party vault app unless you've confirmed the built-in option on your specific platform doesn't cover what you need.
