I've started using Gmail 2 step verification. It works fine from home and also from the office (the latter being the case only if I use Internet explorer).
If I use the latest version of Firefox, I keep getting asked to enter my Google Authenticator password which I obtain from my iPhone app. The problem is, even though I typing it in correctly, it keeps looping or throws me back to the login screen.
I am based in London but work for a Spanish company where my connection (possibly) goes via Madrid. I know that the gmail authenticator codes are calculated I believe on location and time, but I cant understand why it works only on IE in the office and not Firefox. Any suggestions?
Also, to make matters worse, when I try and use any of the other Gmail verification techniques, it wants to use my backup phone to send a text msg to, which is my wife's phone. I dont understand why it doesnt want to use MY main phone.
