Input: I've used the original Yubikey previously on other sites and can attest to its durability. I've had my old Yubikey on my key ring for over 2 years and no issues. I expect this new one to have the same durability. As for the functionality, the Fido U2F Key works flawlessly. I always had an issue with 2 factor authentication when I used someone elses computer. I needed the Google authenticator, or cell phone to get my google codes - now all I do is plug in the Security key. I did have an issue registering it with Google, but that was my fault. It does state you need Chrome version 38. I was using my Asus Chromebox which only has version 36 so every time I tried and register my key, it would time out. I then used my desktop computer which is running Chrome version 38 and everything went perfectly. You do have the option to use the Google Authenticator , codes or cell phone if your device does not have a thumb drive or you don't have your Security Key with you . - One real safeguard is that if you happened to land on a fake Google site through Phishing, the security key will NOI allow your codes to be transmitted -it knows if you are trying to log into a fake site. I'm really looking forward to other sites allowing its use - excellent product

Great  safeguard, very durable
