You can easily change your phone's lock screen to a more secure one with the Front Fingerprint Lock Monitor app. With it, you can set the most common types of locks, including fingerprint, pin, and pattern. You can even set a custom password if you remember it, so you won't have to type in the password every time you use your phone.

If you don't remember the password for your phone, you can set a recovery password so you can still use your phone. You can also set the password to be a certain number of digits, letters, or symbols.

To use the Front Fingerprint Lock Monitor app, you need to first install it on your phone or tablet. You can download it from Google Play.
