You don’t have to use another app-locker if you have Tasker. The following Tasker profile will let you create a lock-screen for certain apps that require privacy. Sounds awesome, right?
- Create a profile and choose Application.
- Select the applications that you need privacy for.
- Name the new task and hit the + button.
- Choose Display > Lock > provide the Lock key in the section.
The next time you open the app, you can see the lock screen. It’s a basic screen, though. It’s very easier than using a third-party app.
