How to switch user quickly, on Mojave? There are two users enabled and used at the same time.
Usually I need to click via mouse the username in the top bar, choose the username2, type in the password.

Am wondering if there's a quicker way.


Like a quick-action callable from the TouchBar; that would benefit also from the close fingerprint sensor over there.
Or maybe simply using a shortcut, that I didn't find yet in the System Preferences. 


Any ideas or insights?
On Mojave it is simpler than I thought.

Clicking the power/fingerprint button will quickly bring the login screen out, with the other user already chosen, ready for the password to be inputed.

After the login it will be possible to switch with just fingerprint-click + fingerprint (for authentication).

That's pretty convenient!

Note: I am not sure if that was active also before, or if the alternative user is chosen based on what are the most active/logged users (because, in my case, the proposed user for login is not the only other user present on the system).
