Log into your Google account on a PC by scanning a QR code via your smartphone
Google recently introduced a fun (and more secure) way to log into your Google account from a public terminal without entering your password into the PC, and instead using your smartphone and a QR code.
This is a neat trick to use when traveling and relying on public computers, and can protect you from a PC with keylogging software that records every keystroke entered into a compromised machine.
Simply navigate to accounts.google.com/sesame on the computer you wish to log into, then scan the QR code that appears with your smartphone using any appropriate app. The QR code will open a URL on your phone that prompts you to log in with your Google account username and password if you are not already cookied. After logging in, the web page will show a warning message, reminding you to proceed only if you scanned a barcode from google.com. You are given two buttons to click, with the options of starting with Gmail or iGoogle. Clicking a button will quickly log you into your start page of choice in the computer’s web browser.
Google’s new QR method is a fun way to get access to your Google account, but don’t forget to log out of your account once you’re done.
