In response to post #31635470. #31635895, #31636295, #31639400, #31641690, #31641935, #31642435, #31659140 are all replies on the same post. Some people here apparently doesn't know how it works... The mentioned solution with Google Authenticator is NOT about sending you SMS, calls, or whatever. It is about an app you have in the phone or on PC (Google is using a well-known standard and there are multiple compatible solutions.) And this app/program in PC generates one time passwords based on current time. So if they decide to use Google Auth, it is probably the best option in terms of compatibility. Of course, it would be nice to add also a support for Yubikey, or some other dongle solution.
