We ask you to set up Google Authenticator as the most convenient and safe way to protect your account. If you have previously used authentication by email or SMS, please switch to Google Authenticator. If you have previously used Google Authenticator, please set it up afresh. 


Go to the Settings section of your personal account and click the "Two-factor authentication" tab. Click the “Get a code” button. A secret code will be sent to your email. Enter it in the “Authorization code” field and click the “Save” button.


A window with a QR code will appear. Install Google Authenticator on your mobile device, launch it and scan the QR code (or use its text version). You will get a numeric code in Google Authenticator.


Click “Complete” in your account and enter the numeric code you received from Google Authenticator to confirm the updated settings. Click the “OK” button.
