This idea strikes me as right. Passwords are unwieldy and hackable in ways that location isn't. However, it's kind of hard to give myself a visceral sense that this would be more secure. It's like how people a generation older than I am like to have documents printed out. I've always felt like something is more secure if it's stored in a digital format somewhere. I lose paper all the time. What if I spill something on it?
HT to D for the video.
I don't really tell my spouse my passwords, but I also don't really care if he uses my devices, usually. I wonder how the actual implementation of this new authetication regime deals with shared devices.
FYI: If this seems like a weird subject for me to be taking on, you might be interested to know that my spouse has taken a job at Google, and we're now living in California. So this kind of thing is on my mind more now.
