WinAuth for Windows or Authy. The steps to activate the feature are the same in both cases.
To enable the Multi-Factor Authentication Device option, follow the steps below:
1. In the My Account → Account Details section, go to Multi-Factor Authentication Device and click on the link add now.
2. Download a MFA app for your mobile device (we recommend Google Authenticator) and scan the QR code that appears on the screen with your mobile device. You’ll need to scan the QR code only when you use this option for the first time.
3. The email address associated to your 123FormBuilder account will appear partly hidden in the MFA application interface of your mobile device (e.g. jo*****@). Under the email address you’ll see a code (6 digits long) and a countdown timer clock on the right.
4. Back in Multi-Factor Authentication Device, enter the code that appears in your mobile device’s MFA interface inside the text box above Activate Code and press the button. Done!
You can disable this option at any time. Return to My Account → Account Details → Multi-Factor Authentication Device and click on Disable.
