My mother will not learn to use a Yubikey, or remember to carry one. You may not believe that (or simply dismiss anyone who won't/can't as unworthy to join in on modern life), but I can assure you it's true.
Have you actually tried this? I’ve found yhe Yubikey model is much easier for normal people because they’re used to using physical keys or cards. What’s hard is a) the cost and b) the hassle of having to pair multiple keys, which is where the biometric phone/laptop based solutions are better since it’s one tap for a familiar prompt.
Yes, as a matter of fact I am painfully aware of my mothers limitations with respect to technology and gadgets, as well as her extensive peer group who I somehow get roped into supporting. Your condescension is noted.
