is it possible to set up more than one phone user on BB10?

is it possible to set up more than one user on BB10? To clarify the term user - I mean that when starting the phone - you enter your password & this is logging in user #1 (like on the windows login screen) but can I get another user #2 login & password?

Settings, Security and privacy, Parental Controls, is one way.
