[ FEATURE REQUEST ] custom PIN instead of device unlocks.

The title explains, however here's the long story:

I have some friends that are able to get into my phone, but the home launcher I use does not support password protected apps, so I would like to suggest that you can set your own pin to unlock hail, min 4 or 6 numbers no max length so they can't access certain apps. 😁
