This plugin is very useful that I recommend it so.
Great with Yubikey!
Perfect, I've felt in love with it. I have a Yubikey, and signing in is just a breeze.
Even More Awesome with Yubikey
Works great! I love the fact that I can now use my Yubikey to secure my accounts.
Solid and Useful
Been using it for about a year with the Google Authenticator app. Works great so far. Have not had to back out any updates as of yet. Keep up the nice dev work.
