So it makes perfect sense that you’d want to use this level of protection and ease for different things.

Supported Devices

If your device has a fingerprint scanner and is running Android 6.0 Marshmallow or higher, chances are your device will support the apps listed below (though some modified versions of Android Android Skins Explained: How Do Hardware Makers Change Stock Android?

The apps listed here use Android Marshmallow’s default fingerprint API, so you don’t need to worry about security. You’re not providing your fingerprint to the app you use. And you don’t even need to scan your finger every time you use a new app — the apps automatically use the fingerprint you’ve already stored on the phone.

1. App Lock

Chalk this one up to the obvious category. Now that you’re used to unlocking your phone with your fingerprint, the next step is to secure your apps. No matter if it’s a messaging app or payment app, an extra layer of security goes a long way.

Next time you open the app, you’ll be met with a lock screen. Simply put your finger on the sensor (the one you’ve already scanned and enabled to unlock your device). It will be recognized and you’ll be in.
