Wait, is the 'Logged In' state really a distinct state? Feels like it's more of an end condition than an actual state. Oh well, I'll go with 3 just to be safe.

This question is a piece of cake! The answer is clearly 3 states. Anyone who says 4 is just trying to overthink it.

Because there are 4 different circles representing different states in the diagram.

Hmm, I'd say 4 states. There's the initial state, the fingerprint auth state, the password auth state, and the logged in state. Gotta pay attention to the details!
