comment Login mechanism for multiuser smart-phones/tablet
If the question is having a password unique enough (as fingerprint and retina scan) would be enough having a password long enough or lets say... a signature?

Do you easily remember a sequence of digits? Since it is a password provided by the system, you should remember it just after seeing and typing it for less than a minute. The very first thing that I (personally) do when I get a pin is changing it (and I don't share a single password between accounts)

Oops! I missed the critical suggested by the system Sorry! Now another question: is a password suggested by the system a good UX (might be hard to remember)?

As far as I see it, pattern lock replaces pin/password but does not solve the question of multiple users accessing the device.

System (I've updated original question for including more information about a possible scenario)

comment Computer login with password only, without username
But OP started saying "I have an idea to simplify the login screen on things like home computers with a small number of users (say, 2-10) with passwords." there you have device / username. (Anyhow, I don't pretend to argue on this, just pointing that we are using it many times for single user devices)

@JohnGB I tend to agree with the poor security and I'm sure I would not go with that idea for something that I will have to be responsible of but this is (somehow) being used in devices like phone, ipads, credit-cards,... I only need to know the PIN (password) not the owners name or phone number. So I would say that this idea is actually widespread.
