Teamviewer connected with id assigned but without password

Hello all,

as in the title, the pc is connected to the Teamviewer lan (it's the pc to whom i need to connect, and is on line trying to connect to its Id) but in the "Pasword" tab there is a " - "  

I have tried to launch it in Administrative's right but nothing different happened

How can i solve it? 

Thank you
