You can absolutely do this with Xiaomi phones. You can set up a second password in order to access what is virtually a completely different phone.

You can even set a different fingerprint so that different fingers unlock different profiles.

The feature is called Second Space

Somehow, I find it ironic that you have to buy a Chinese phone to get this feature.

I believe some Android ROMs do come with passwords that when entered wipe out everything on the device.
