How to lock apps and files behind your finger

Fingerprint scanners make it easier than ever to secure your smartphone, reducing the need to enter a PIN every time. Whether you are locking or unlocking your device or logging into apps, it's really one of the most convenient features on today's phones.

There is also another use for biometric security on smartphones, with fingerprint lock functions as a popular feature days. Whether it's your social media app or nasty pictures, let's see how to lock content behind a fingerprint.

We start with a guide on how to unlock apps and content on OEM skins that offer the feature and also look at some of the best fingerprint lock tools in the Play Store.

Huawei

Huawei was one of the first to adopt a fingerprint-safe, similar to Ascend Mate 7 and other phones in his stable. Locking content behind a fingerprint has been a staple of Huawei phones and the latest devices still offer it.

To enable the feature on your phone, visit Settings> Security and Privacy> Fingerprint ID . From here, enable Access Safe and Access Lock options .

To enable the fingerprint lock feature, you must visit Settings> Security and Privacy> App Lock then select which apps you want to hide behind a fingerprint. Now, when you tap a locked app, you will have to verify with your fingerprint to launch the app.

To access your file safe, visit Settings> Security and Privacy> App Lock or open the file's app and press Safe . To add something to the checkout, open the file's app, hold down the current file and press More> Move to Safe .

OnePlus

The flagship manufacturer has offered fingerprint scans since OnePlus 2, but they are not only used to lock and unlock the phone. OnePlus has delivered fingerprint lock functionality for a few years now, called App Locker.

To find this feature, tap Settings> Tools> App Locker . Enter your PIN to continue, and you can select Add apps to, yes, add apps. The site also gives you a switch to hide notifications from these apps. Now, when you want to start one of these apps, you must enter your data or use the fingerprint scanner.

OnePlus also had a SecureBox feature for your private files, but users last year noted that files could be accessed through a separate file manager app. The company recognized the problem and updated the function shortly after, while giving the name Lockbox instead.

In any event, you can find the file safe by visiting File Manager> Categories> Lockbox . Once you have tapped it, you must enter a PIN to access it for the first time, but you should be able to use fingerprints for subsequent attempts. If you want to add content to the file, it is important that you keep the current file and then tap The three-point menu> Move to Lockbox .

Oppo

OnePlus is not the only brand BBK offers biometric recognition. Recently, this feature has been offered.

To activate the feature, visit Settings> Fingerprint, Face and Password> Privacy Password . Once you have tapped the last option you will find the option to Turn on the Personal Protection Code . Press the option, enter the desired code, verify the code and select a security question if you forget the code. You should carefully tie an email address for peace of mind as well.

After completing this process, you can access both private (file) secure and fingerprint lock options from the private code or Settings> Security> Lock / Private Safe . Point to the app lock option to select which apps require a fingerprint to boot, while pressing the private secure option, you can (surprise) see your stash of private files.

Unlike some other OEM users on the list, the Oppo does not appear to display the file's secure options in the built-in file manager. Instead, the standard solution is to visit the above menus to see it. However, you can create a shortcut shortcut by visiting Private Safe tap Cog and enable the switch for Home screen shortcut
