I just got the two factor system while logging on to MDE. I don't mind it, it maybe adds 5 seconds to the process. And I'm all for not getting hacked, especially if I'm in the middle of a vacation.
I'm curious if this, in addition to security, is an effort to cut down on those services that track availability across the different platforms. I've never struggled so much to get reservations for our trip next week, it's ridiculous how hard it's been. Those that are paying for the services that either notify or actually make dining reservations for them seem to have a lot of success.
