While our phones are great for accessing Google services, nothing beats the experience of doing it on a desktop computer especially when you have to edit documents or spreadsheets in Google Docs. But what if you’re not at home and only have access to an untrusted, public computer that may or may not have keyloggers installed? Google has come up with a simple solution to the problem: a QR code-based login system.
All you have to do is head to the Google Sesame page, scan the QR code with your smartphone, access the website there and login on your phone. Once authenticated, you’ll be able to launch Gmail and any other Google service on the computer – all without having to even type your own username or password on the untrusted computer! A pretty nifty trick for all those paranoid folks out there worried about using public computers.
