So with the recent hullabaloo over the phishing attack on gmail users, I thought I’d take the time to setup the two step verification process for my account. Its very easy since I already have an Android phone. So first download the Google Authenticator(and the Barcode Scanner from ZXing Team, as thats how the app scans QR codes). Then from your Google account settings page, click the link that says 2-Step authentication.
Tell it you have an android phone, then with the app, scan the QR code(which I’m figuring is some unique seed value that allows the app to create a random code without requiring network access). Then the app will give you a code and you use that to login. Very easy. It will give you a backup list of codes to print out in case you lose your phone.
Though one thing that isn’t obvious is that once that’s done, you have to setup an application specific password to login on Android. But even that is very easy. All in all, it looks like a rather secure setup. So if your a paranoid or just someone who is aware of the dangers of being online, this is a good thing to have.
