A patent troll who purchased a 2016 patent has filed an infringement claim against Apple for the Auto Unlock feature, originally designed to allow an Apple Watch to unlock a Mac using the same Apple ID.
This is despite the fact that the patent application was filed after Apple announced Auto Unlock …
Background
Apple first announced Auto Unlock at WWDC back in June 2016. Users need to have two-factor authentication enabled for their devices. Once that’s set up, you can enable the feature in System Preferences.
