A free app for Android, by highsecure.

Developed by highsecure, Photo keypad lockscreen is a unique app that lets you customize the lock screen.

This app customizes your screen in the most extraordinary way so that instead of finding numbers for your usual pin code, you are going to find pictures of – whoever you want to become your pin code. And so instead of having a 7645 password, you can instead opt for a Jin – Jimin – Suga – RM code, or a Jisoo – Jennie – Lisa – Rose one.

This app also features a large assortment of stunning wallpapers to choose from, a cropping and resizing function, and so much more.
