I am thinking about getting an Apple Watch. One of the most interesting features is Auto Unlocking of Mac. Does Apple Watch auto unlock need network and two-factor authentication?
The AirDrop function says it needs open Wi-Fi. I used to think that it needs a network. Later I found that two devices need not be connected to a common access point for AirDrop to work. So I think network isn't necessary.
Another problem is the Two-factor authentication. Is it necessary? My password is very secure and I don't want to enable this feature. Apple's help page says Make sure that your Apple ID is using two-factor authentication instead of two-step verification. I don't understand what this sentence means. Should Two-factor authentication be turned on or must not use two-step verification?
