The option to use Apple Watch to unlock mac has disappeared?!
I can no longer use my Apple Watch to unlock my macs (iMac and Macbook Pro). The option has just disappeared from Security & Privacy:
Apple Watch Series 3, watchOS 6
Nevermind, I was unaware that my apple watch had to be signed in to my Apple ID. Thought that happened automatically through the phone :)
Weird that it got logged out though :)
