John raised the problem he’d had with implementing Two-factor authentication on his Mac during a recent upgrade (to High Sierra, I think). Now Two-factor authentication is generally a good thing when you’re talking about access to cloud based services, eg OneDrive, eMail, Google Drive, iCloud – but it seems a bit OTT when you’re talking about an operating system as protection to prevent access to services running on the hardware. But Apple doesn’t make this clear.
When I was doing my High Sierra and iOS upgrades the other day I was prompted to ask whether I wanted to implement Two-factor authentication, but was also advised that some of my devices wouldn’t support it and I would lose access to services if I chose to implement it. That was enough to warn me off, so I didn’t. John was not scared off – possibly because he didn’t get the warning that I got – and has had to make a trip to the Apple Store to try and get it sorted.
Two-factor authentication is a “good idea”, don’t get me wrong, but Apple’s implementation is a bit clunky it would appear.
