If any of you have a Google\/GMail account I am sure you have seen the prompts to setup 2 factor authentication (2FA). The way 2FA works is that not only do you enter a password, but a pin is sent to you via SMS and you have to enter that, too in order to login. When I first saw it I was tempted but then I thought (like any sensible person would) that if my mobile phone runs out of battery or if I am out of network coverage, I won’t be able to access my emails. So I left it at that.<\/p>\n
Then a few days ago whilst I was attending the WordCamp San Francisco (remotely, via streaming) during one of the presentations somebody mentioned Clef<\/a>.\u00a0Clef<\/a> is a combination of a mobile phone app and software that lets you login to websites without even entering a password. So, when you want to login you see some vertical lines moving up and down on your screen, you open the Clef app<\/a> on your mobile phone and you point the camera to the screen. The app reads the lines and sends a coded message to the Clef server. The Clef server confirms with the site that the coded message is correct and the server sends a message back to the app where you choose for how long you want to be left logged-in into the website; you can even choose infinite time. And that’s it! You are logged in and ready to work. There is a Chrome extension, called Waltz<\/a>, that allows you to use Clef even on the websites that don’t have the Clef technology installed. I am quite happy with it, the only complain is that you cannot be logged in one computer and login to another, too. You will have to log out from the first one to login to the second. A nice feature is that you can logout remotely through\u00a0the mobile app.<\/p>\nPros:<\/h4>\n
