Lock Apps with PIN or Fingerprint (without any App) in OnePlus 3/3T

Noticing the importance and demand of app lock facility, OnePlus has decided to bake the feature within its operating system. OnePlus now allows users to lock individual apps on OnePlus 3 and 3T smartphones running  Oxygen OS. The locked apps can then be unlocked either via the fingerprint or the PIN code /password set to unlock the phone. Unlike some 3rd party apps which can be bypassed some way or the other, the inbuilt mechanism provides more reliability.

Locking Individual Apps on OnePlus Devices

The process to lock apps is pretty straightforward and does not involve downloading any apps. The PIN code to unlock apps stays the same as the one set to unlock the phone. So, if you want to set a different PIN, you should consider using a third-party app. Follow the steps below to lock apps on the OnePlus 3.

Applies to: OnePlus 3 running Oxygen OS 3.5.x or higher. Oxygen OS 3.5 is currently only available for OnePlus 3 as community (beta) build.
  1. Make sure that you’re running Oxygen OS 3.5.4 or higher.
  2. Open Settings > Security & Fingerprint.
  3. Scroll down and choose App locker under Privacy.
  4. Confirm your PIN code.
  5. Enable the toggle in front if the apps you want to lock/encrypt.


    Choose Apps to Lock

That’s it. All locked apps will now require fingerprint unlock after you lock the screen.

Currently, there are no additional settings to require fingerprint every time you launch the app. You also cannot set a custom fingerprint or PIN code for the locked apps.

Are you making use of the feature? Do let us know if you find it useful. If not, what you’re missing? 🙂

          That’s strange. So you enable App Lock for WhatsApp and it is still unlocked when you go ahead and open it?

    I updated to Oxygen Os 3.2.8 virsion and don’t find the “App Locker” at this location.
    Is anybody know where i can find it?

      Hi Evi,
      The feature was introduced after Oxigen OS 3.5.5. So, you will not be able to find it in 3.2.8.

          Actually, OnePlus is currently pushing the Nougat update (Oxygen OS 4.0.1) for OnePlus 3/3T devices. It might be so that your region has not yet started receiving the update.
          3rd party apps are good, but they can be removed. So unless you lock settings, Play Store and all other means to remove or modify the app, you might be in limited security.
