To use an app lock with fingerprint authentication, you generally follow these steps:
- Install an App Lock: Download and install a compatible app lock application from your device’s app store. Many options are available, some of which may be free.
- Initial Setup:
- Open the app lock and follow the initial setup prompts. This will often involve creating a master password or PIN as a backup method.
- Grant the necessary permissions to allow the app lock to access and control other apps on your device.
- Enable Fingerprint:
- Navigate to the settings menu within the app lock.
- Look for the option to enable fingerprint authentication. You might need to have set up fingerprint security on your device previously.
- Choose Apps to Lock:
- Select the applications you want to secure with fingerprint authentication.
- The app lock usually presents a list of installed apps, allowing you to toggle the lock on or off for each.
- Using the Fingerprint Lock:
- Once an app is locked, launching it will trigger the app lock. You will have to verify your fingerprint to gain access.
- According to the reference, the app will ask for a password if the fingerprint isn't available, and then, the fingerprint may be used to unlock it.
Example:
Suppose you want to lock your messaging app. Here’s what it might look like:
- You open your app lock application.
- You select the message app and activate the lock function.
- Next time you open your message application, you are prompted to authenticate with your fingerprint.
Troubleshooting:
If the fingerprint authentication isn't working:
- Make sure your finger is clean and dry.
- Ensure you have properly set up and registered fingerprints in your device's security settings.
- If you have difficulty, the password/PIN should still work as backup security.
