easier to implement than SMS Maybe for the IT group. Not for the end-user. SMS MFA on Apple is so easy it's ridiculous. The OS autofills the MFA form with the received value. There's nothing for the user to do beyond flipping a switch in settings to allow SMS messages to pass through from phone to Mac or iPad. Versus any other MFA system, which requires manual intervention. Yubikey - either have to read the code and type it manually OR tap the device (if you're on a laptop with an open USB port). App-based - have to open the app and copy/paste or manually enter the code. Etc.
