I love U2F and wish more websites supported it. I bought two nano YubiKeys (they fit almost completely inside a USB port, just sticking out enough to touch the capacitive edge or dig out with a fingernail). I keep one in my laptop and one on my keychain (the keychain one also has NFC which, someday, should let me authenticate my phone). Chrome's U2F support has worked flawlessly for me — when a website wants to register or check the token, an LED starts flashing and you touch the edge of the token to give it permission to respond. That's it — no more digging for my phone to get codes. I was also relieved that this isn't a list of software that [requires a dongle to run](https://en.wikipedia.org/wiki/Software_protection_dongle https://en.wikipedia.org/wiki/Software_protection_dongle) :).
