Fingerprint scanners make it easier than ever to secure your smartphone, reducing the need to type in a PIN code every single time.

There’s also another use for biometric security on smartphones, with fingerprint app lock functionality being a popular feature these days. Whether it’s your social media app or other sensitive content, you can easily lock it. Some of the most popular smartphone manufacturers have already given this feature by default in their smartphone, let’s look at how to lock content behind a fingerprint.
The guide ahead has been sorted depending upon the smartphone manufacturer. Different brands utilize different names and methods to let users lock files and apps with fingerprints but thankfully, we have them all listed for easier referencing.
How to Lock Files and Apps with Fingerprint
As we mentioned above that some of the manufacturers have provided in their phone by default so lets start with them first.
For Huawei Smartphones
Huawei was one of the first to adopt a fingerprint safe, seen on the likes of the Ascend Mate 7 and other phones in its stable. Locking content behind a fingerprint has been a staple on Huawei phones and the latest devices still offer it.
To enable the feature on your phone, you’ll want to visit Settings > Security and privacy > Fingerprint ID. From here, you enable the options for access safe and access app lock.
To enable the fingerprint app lock functionality, you’ll need to visit Settings > Security and privacy > App lock, then choose which apps you’d like to hide behind a fingerprint. Now, whenever you tap on a locked app, you’ll be forced to authenticate using your fingerprint in order to launch said app.
In order to access your file safe, you can visit Settings > Security and privacy > App lock, or open the files app and tap on Safe. If you want to add something to the safe, open the files app, hold down on the file in question, and tap More > Move to safe.
For OnePlus Smartphones
The flagship manufacturer has offered fingerprint scanners since the OnePlus 2, but they’re not merely used for locking and unlocking the phone. OnePlus has delivered fingerprint app lock functionality for a few years now, dubbed App Locker.
To find this feature, you’ll want to tap Settings > Utilities > App Locker. Enter your PIN to proceed, and you can choose Add apps to, well, add apps. The page also gives you a toggle to hide notifications from these apps. Now, any time you want to launch one of these apps, you’ll need to enter your credentials or use the fingerprint scanner.
OnePlus also had a SecureBox feature for your private files, but users noted last year that files could be accessed via a separate file manager app. The company acknowledged the issue and updated the feature a short while after, while also giving it the Lockbox name instead.
In any case, you can find the file safe by visiting File manager > Categories > Lockbox. Once you’ve tapped on it, you’ll need to enter a PIN in order to access it for the first time, but you should be able to use the fingerprint for subsequent attempts. To add content to your file safe, you need to hold on the file in question, then tap Three-dot menu > Move to Lockbox.
For Oppo Smartphones
To enable the feature, visit Settings > Fingerprint, face and passcode > Privacy passcode. Once you’ve tapped the last option, you’ll find the option to Turn on privacy passcode. Tap the option, set a desired code, verify said code, and choose a security question in case you forget the code. You should probably bind an email address for peace of mind as well.
Once you’ve completed this process, you can access both the private (file) safe and fingerprint app lock options from the privacy passcode menu or Settings > Security > App lock/private safe. Tap the app lock option to choose which apps require a fingerprint to launch, while tapping the private safe option lets you (surprise) view your stash of private files.
Unlike some other OEMs on the list, Oppo doesn’t seem to display the file safe option inside the native file manager. Instead, the default solution is to visit the aforementioned menus to see it. However, you can create a homescreen shortcut by visiting the Private safe, tapping the Cog, and enabling the toggle for Homescreen shortcut.
For Samsung Smartphones
Samsung has long had fingerprint app lock and file-hiding capabilities, calling it Secure Folder, and it’s a pretty comprehensive solution.To get started with the feature, you’ll need to tap Settings > Lock screen and security > Secure Folder. From here, you’ll need to sign into your Samsung account or create an account if you don’t have one.
These are the smartphone manufacturers in which we found the fingerprint lock for apps and files feature.
