The "bad" news is that if you have a Mac with Touch ID, you get three options instead of two. You can press the side button of your Apple Watch twice to authenticate, or click Use password … to do just that. Every time the Mac needs your administrator password (the one you use to log in to your Mac and to authenticate when you change certain settings), you will get a small touch on your wrist and this dialog box will appear on your Mac's screen: (Almost) never retype your password. And the good news is that if you already use your Apple Watch to unlock your Mac automatically, then you don't need to do anything. This tip comes to us through Mac writer Kirk McElhearn.

Wouldn't it be great if you could do the same with your Mac login password? Instead of having to type your password to authenticate, you could double-tap the side button on the Apple Watch to do so instantly.
