This is the best and most complete app for lock screen, gallery, and vault apps to secure folders with the gallery lock app.

Gallery Lock helps you to protect your personal photos and videos, hide apps with a unique password, create a secure vault for your app and folder, and protect apps and private vaults.

You can secure the app and its files with the fingerprint lock, password lock, or a combination of the two. The fingerprint is used to identify the user and the password is used to protect apps and files with a fingerprint. The fingerprint will be shown on your lock screen to start your locked photo vault.

To secure your files, create a unique password to lock your apps.

Please note, that when you use the fingerprint lock, the device will not be set as a secure folder when you start the app.

You will be required to enter the password to open your locked photo vault.

If the password is not enabled for the app, or you want to try again, you can enable it in app settings >> Enable fingerprint (your device should support fingerprint)

This app will not work with Android 5.0 or below, so please make sure you have a device with Android 6.0 or above.

Please note that the locked photo vault is intended for personal use only, and it is not intended for commercial use.
