How much would it cost to pay someone to "break open" my GMail account if I lost access to all my second factors? I'm guessing more than the ~$150 a locksmith would charge me to break into my house. Probably a number of zeroes at the end more.
But even in the physical world, how often do you lose your house or car keys? I can't remember if I've ever lost them for good and had to pay a locksmith. It just doesn't happen. I do have a spare of each key (or another type of key like a garage door opener) I'm case it does happen. Why does everyone bring up the problem of lost keys when it comes to computers? It's no t that big of a deal. I know I've lost or forgotten far more passwords than I have physical keys over the course of my life. Am I that different from the average person?
