Googler Extraordinaire Matt Cutts made a call for users to enable two-factor authentication for Google accounts and that is a great idea for some users however I think power users are going to find it hard to make a leap to two-factor unless Yubikey is natively supported by Google which it currently is not.
The problem currently is that you need to use either the Yubico App (Windows) or this snazzy Python Script (Linux) to have Yubikey work with Google Two-Factor but if you happen to be using a friend’s laptop or be at work or perhaps a Library the likelihood of you being able to run one of these workaround applications is very unlikely.
Strong authentication practices is something every consumer or enterprise user should strive for while at the same time service providers and vendors also need to adopt widely used technologies that safeguard users and in this case this is something Google should strive for. Afterall, we don’t want to see more victims like this do we?
Surely there is a Googler who would love to spend their pet project percent time on implementing native Yubikey support?
