AppLock is a useful tool that allows you to protect your privacy and lock apps with a password. You can also use fingerprint or pattern lock. It is a great app to help you secure your privacy on social networks like Snapchat, Instagram, Facebook, Twitter, etc.

To use the fingerprint or pattern lock, you have to enable the fingerprint or pattern lock in the settings of the app. You can find the settings in the app itself. To change the password, you need to open the app and click the “forgot password” button.

Please enable Advanced Protection in the protection of AppLock, so nobody can uninstall or kill AppLock without a password. You can disable Advanced Protection when you don’t want it.
