Happy new year 2017 to everybody!
You may run into a situation where you are working on the desktop (or laptop) computer but the mobile phone, that is required for generating one-time passwords, is another room or you probably left it at a friend’s place.
Keep in mind, though, that using a two-step authenticator app is less secure on your computer. Anyone who has access to your desktop can get your security key and log into your account.
But if you don’t own a smartphone, using a program on your computer is better than nothing.
Not a problem as you can also generate verification codes in your desktop browser without requiring the Google Authenticator app. All you need is is the GAuth add-on for Chrome and you are good to go. The only difference is that instead of scanning QR codes, here you will have to enter the 16-digit secret key to add an account manually.
The security tokens are stored locally in your browser using HTML Local Storage and thus you don’t have to enter them again.
Now go to below this link to add Authenticator to your chrome browser (If you don't use chrome browser, you can access here to download it)
Add your secret key and choose Time Based to Authenticator addons (or you can scan QR code)
