Good idea Krusaderx! The IPs are unlikely to change any time soon, unless we somehow run into a problem like we had several months back with one ip failing to route properly every now and then (it was very strange) - should likely be static for awhile.
In other news, in addition to adding Yubikey as a 2nd factor authenticator, I have now activated Google Authenticator for those of you who don't want/don't have a hardware token to use. You can now download the Google Authenticator from your favorite market (Either Android Market, Apple Market or BlackBerry Store), install it on your mobile device and use it as a 2nd factor authenticator.
See this link for more information:
http://support.google.com/accounts/bin/answer.py?hl=en&answer=1066447To activate GA, you will need to go to My Account, click the Google Auth radio button and save your changes. Then you will need to generate a GA token, with the link right below the 2F Auth for Google Authenticator. You will be presented with a QR code that you scan into Google Authenticator and it will automatically configure everything you need.
I've tested it out, but I am tired and it's late, so it's entirely possible I missed something. For anyone brave enough to give it a try, let me know what you think. If for some reason you get locked out of your account through a bug, send me an email and I will unlock your account as soon as I wake up. I am going to bed now though!
Quite a day for blocks!
