You can set up Two-Factor Authentication (2FA) on the Security page > 2FA Settings.
Open your 2FA application and either use the phone camera to scan the QR code or enter the code manually.
Please wait for a new code to be generated and insert it in the "Enter the Two-Step Authentication code" section and click on the "Verify Code".
Your 2FA Authentication security feature is activated.
If you prefer to set the 2FA Authentication using SMS code, please click on the "Alternative Authentication Methods":
In the window which opens after you click on the "Enable" button, please choose the country, provide your phone number and click on the "Verify" button.
Enter the code from the SMS you will receive and click "Verify":
The speed of SMS verification varies from country to country. For instant codes and additional security, please use an app like Google Authenticator or Authy for the 2FA codes.
Please be informed that completion of the Personal Info section of your account verification automatically activates your 2FA using SMS as an authentication method. Should you wish to, you can later change this from “My Profile” > “Security” > “Two-factor authentication”. For detailed steps on how to do this, check this article.
