Time Password - Screen Lock is a free Android app developed by Milan Apps Development. It falls into the Utilities & Tools category and provides a simple yet effective way to secure your phone with a lock screen system.

The app sets the live time as a password, making it difficult for anyone else to unlock your phone. To unlock the phone, you have to add the time shown across the screen. This way, nobody except you can unlock your phone, ensuring complete security.

Additionally, the app offers features like custom lock screens, lock settings (sound, vibration, reverse password), different wallpapers, and the ability to change the app icon and name. The app is fully customizable and can be used to secure your phone with ease.

One thing to note is that if you are a Xiaomi / MI phone user, you will need to allow all the permissions and set up the app to auto-start for it to work properly.

Overall, Time Password - Screen Lock is a reliable and secure lock screen system that is easy to use and customize.
