How to Lock Apps Using Fingerprint Sensor on Your Samsung Galaxy S7

The fingerprint sensor on an Android phone is no longer just a luxury but a necessity. It provides an easier way to unlock your phone without the need to remember a PIN or password. Additionally, it can serve as an additional input device that allows you to do much more with your phone.

While some users may feel that the lock screen is enough to keep prying eyes away, others prefer to use third-party apps to lock access to specific apps like WhatsApp or the Gallery. If you own a Samsung Galaxy S7, you can take advantage of the fingerprint reader to enhance the security of these apps.

App Locker: Fingerprint

One of the top apps that you can use to lock other apps with fingerprint security on your Samsung Galaxy S7 is App Locker: Fingerprint. This app delivers on its promises and is easy to set up.

After installing the app from the Play Store, you will be prompted to authenticate your fingerprint. It takes the data from the fingerprints you have configured in the system. Once authenticated, you need to enable two settings. Firstly, you need to grant the app Accessibility Settings permission to gain access to other running apps. Secondly, you need to activate Device Administrators control for uninstall protection.

Once you have provided the necessary permissions, the app will display a list of all the apps installed on your device, including system apps. To enable fingerprint security for an app, simply toggle the button next to it.

From that point on, whenever you launch any of the locked apps, you will be prompted to authenticate your fingerprint before the app can be launched. The app works flawlessly without any ads, and it even prevents peeking into recent apps. However, keep in mind that the app relies solely on the fingerprint sensor, meaning there is no failsafe if your finger is injured or if someone else needs to unlock the phone.

If you find yourself in such scenarios, you might want to look for an alternative, which is discussed next.

App Lock: Fingerprint & Password

App Lock: Fingerprint & Password is another app that allows you to lock other apps using fingerprint security on your Samsung Galaxy S7. This app offers additional features that make it worth considering.

While the app can be installed and used on any device to lock other apps, the fingerprint security feature is only compatible with Samsung devices. If the fingerprint sensor fails to capture your fingerprint, you can still use a pattern or PIN as an alternative method to unlock the apps. This way, you can share the PIN with someone you trust when necessary.

The app reads the saved fingerprints, and you can enable this option in the settings. You also have the choice to re-lock recently unlocked apps immediately or wait for some time to minimize irritation. Toggling the apps on or off in the list is all it takes to lock or unlock an app.

App Lock also provides uninstall prevention, so no one can remove any app from your phone, including App Lock itself, without your permission. For an extra layer of security, you can activate the app as a Device Administrator.

Do Even More with Marshmallow

These two apps cover everything you need to make your Samsung Galaxy S7 more secure by adding 2-factor authentication to the apps you want to protect. Additionally, it’s worth noting that the Samsung Galaxy S7 comes with Marshmallow, which makes it compatible with Nexus Imprints. This means you can use the fingerprint sensor directly on apps like PayPal and LastPass to enhance their security without the need for any third-party apps.
