It allows you to open different apps or launcher shortcuts using different PIN codes/patterns
This is NOT for security, infact it reduces security (more passwords, so more chance of getting it right)
It simply allows you to set shortcuts
Set 1111 as password for "Phone" app
Set 2222 as password for "Messaging" app
Set 0000 as normal password, from Android Settings app
Then, when I type 0000, it will unlock as normal
When i type 1111, it will unlock and then launch "Phone"
When I type 2222, it will unlock and then launch "Messaging"
It should work with PIN and password and now also patterns!
