Gee, so many "friends" who want to hold onto our keys for us. Sounds like a rehash of "firefox accounts", oAuth, yadda ya AFAICT, the "FIDO" standard has already won. Soon we'll be expected to "here, plug in this blackbox 2FA usb dongle we give ya" (freeFREEfree! cuz you're one of our premier special snowflakes) No? Tough luck, then. Your "old-fashioned" login won't be permitted by Amazon, PayPal, ChaseBank, Google...
I'm not sure what to think yet, I must do some more reading, but sounds interesting. I would like to hear other peoples opinion, who have a bit more knowledge on this subject.
