The bad luck is that your smartphone needs a fingerprint scanner to make full use of this API.
Once such developer is Rick Clephas, who used the API to provide superb locking system for Android Apps.
On the second page of this tour, you will get a chance to double-check your devices compatibility.
Tap Check Compatibility here, and if you see a big green check mark, then proceed further.
Then, you will be prompted to create a backup password.
Lastly, FingerSecurity will ask for Usage Access.
So, tap Open prefs on the screen, then press OK on the following menu.
From the Apps tab in FingerSecuritys main menu, tap the floating action button in the bottom-right corner.
Enable this option to only lock certain screens within the app, and you will notice a popup.
The entries in this list are activities, which mean that their names are not simple to decode.
All you gotta do is simply scan your fingerprint to access them.
