Just for the fun of it, I figured I'd try to log in and see if Google has any info on stuff I've purchased. I'm over VPN so they insist this device isn't recognized (even though I've signed in from this exact machine, over this exact VPN connection, last week). Google helpfully offers to send me a security code over the phone. Even better, though, it has a "Can't use your phone?" option. You know what happens if you click that option? It takes you to a screen that says "You're trying to sign in on a device Google doesn't recognize. For your security, use your phone to show it's you signing in and not a hacker." and the only option on that screen is "Go back & use phone." I think there's a joke about how to understand recursion here but I can't quite put my finger on it yet.
