What is Google Auth? Is it safe? What should I do if I dont have an access to Google Auth to pass 2FA?

Google Auth/Authy are safe and secure dual authenticator apps, and available for iOS and Android platforms. You can download and login to DRGx >Settings>Accounts section to activate it and scan the QR code using Google Authenticator or Authy. Please make sure you don't lose the device else you will lose the access of platform. In case if you lost the device you need to go through the verification process and it may take 3 to 7 business days.
