TFA (Two-Factor Authentication) a.k.a., 2FA

Something I mentioned in answer to a question about hacked websites and hacked Gmail this morning, while I thought it relatively new, has (now that I think about it….) been around for many years! By that, I mean decades. Way back when, before the Internet was known to so many people, we had really cool two-factor authentication services up and running at Lockheed Missiles and Space Company, in Sunnyvale, CA.240px-lockheed-logo_winnie-mae

So, enough with the history, already….

Today, you can find many purveyors of this security feature. Below, I’ve included links to two articles on Google’s offering and two articles on Apple’s versions. Enjoy!
