How to Lock Apps on Android, No Extra App Needed
Android has no universal app lock, but you don't need a shady download. Use screen pinning, Private Space, Secure Folder, or a built-in App Lock.
Android has no single switch that locks every app, but you don’t need a sketchy download for the ones that matter. Pick by goal: pin the screen for a handoff, move private apps into a lockable Private Space or Samsung Secure Folder, or use the App Lock many makers build in.
Lock the phone to one app
Screen pinning sticks the phone on one app until you enter your PIN, so a borrower can’t reach your messages. Turn it on under Settings > Security & privacy > App pinning (Samsung calls it Pin windows, under Other security settings), then require your PIN before unpinning. To pin, open the app, swipe up to the recent-apps view, tap the app’s icon, and choose Pin; to unpin, swipe up and hold, then enter your PIN. It locks the phone, not the app itself.
Move private apps into a locked space
For a true per-app lock, use a separate space with its own screen lock. On Android 15 and up, open Settings > Security & privacy > Private space. On Samsung, use Settings > Security and privacy > More security settings > Secure Folder (a Samsung account is required). Both make a hidden, PIN- or fingerprint-locked area; apps inside are stopped when locked and vanish from the app drawer. It’s a step past hiding apps on Android, which only removes icons.
Use your phone’s built-in App Lock
Many skins include a real per-app lock, so check before installing anything. To find it fast, open Settings and search “app lock.”
| Phone brand | Where App Lock lives |
|---|---|
| Xiaomi / Redmi / Poco | Settings > Apps > App lock |
| OnePlus | Settings > Utilities > App Locker |
| Oppo / Realme | Settings > Privacy > App Lock |
| Samsung | Secure Folder (no separate app lock) |
| Pixel | Private Space (no built-in app lock) |
Set the lock code different from your screen-lock PIN, since a strong, separate password is the point. If you use a fingerprint, keep the sensor working so you aren’t locked out.
Skip most third-party lockers
Play Store “app lock” apps often want accessibility and usage-access permissions that let them watch what you do, and several can be bypassed from the recent-apps screen. Try a built-in option first and check the permissions before trusting one.
Start with what your phone offers: pinning for a quick handoff, and Private Space, Secure Folder, or App Lock for anything behind its own PIN.
