use the touchbar on your MBP to sudo

just came about this tweet from @cabel: Pro MacBook Pro Tip: have a Touch Bar with Touch ID?

Edit 28.05.2019: in iTerm 3.2.9 you have to set under “Preferences/Advanced” the value of “Allow sessions to survive logging out and back in.” to “No” for this to work.
