If you are connecting via VNC / ARD client to a macOS system with mutliple GUI sessions.

If the screen saver is enabled on the account and it locks the screen, any subsequent connections will be in 
a stuck state, you will not be able to type or even access the screen saver password dialog box. It is like the system 
will not recognise any movement. 

Provided you have SSH accesss to an admin account on the system and you have no unsaved changes, 
you will be able to force logout the GUI enviroment using the command below : 

   $ sudo launchctl bootout gui/$(id -u <usercode>)
