The AppLock iPhone app allows you to set a password for any app on your phone. To do this, download AppLock and search the Internet for a picture with an icon of the application for which you want to create a password.
Then download the picture you have found to AppLock, enter the name, select the desired application from the list, set the password and click “Create icon”.
Add the created icon to your home screen by following the instructions on the website. The application itself can be removed from the screen.
Great, now when you click on the icon from the desktop, you will always be asked for your password, and any outsider who takes to your phone will be puzzled that they can’t log into the app that easily.
