There is a Yubikey model that uses NFC called the NEO[1]. So it would operate simply by your being close to the computer. At the moment, the NFC only works with Android, iOS, Windows Phone, and Blackberry, but it might be able to be ported easily. I'm looking into how this might help you now (Yubikey has an SDK). You're on OSX, so let me see what I can come up with. No promises, but I'm looking. 1. http://www.yubico.com/products/yubikey-hardware/yubikey-neo/integrate/ http://www.yubico.com/products/yubikey-hardware/yubikey-neo/... EDIT: I see that the Yubikey NEO is sold out for the next 5 weeks, so this may not be the best option for you. EDIT2: The best solution was referenced by silverlight above, it's called TokenLock for Mac OSX, and it's $3 in the App Store. You can use it with bluetooth devices. Just get some little $20 bluetooth device or headphones you can pair it with, and have someone put it in your pocket. Please take a look here (again, thanks to poster silverlight above): http://www.map-pin.com/tokenlock-home/ http://www.map-pin.com/tokenlock-home/ Never used it, but it looks pretty versatile and can be used with all sorts of login approaches. For securing your browser passwords, I think the Yubikey with the NFC chip will be your best bet. Right now, they don't have OSX software available specifically for the NFC, but I imagine they will release some eventually. I'd call and ask them.
