How to Enable Two-Factor Authentication
Two-factor Authentication uses a code verification method to confirm the user identity for a secure Knowledge Base Account. In ProProfs Knowledge Base, enabling two-factor authentication ensures an extra layer of security for your account.
Here is how it works:
Enter the login credentials of your ProProfs Knowledge Base account as you regularly do, then enter the six-digit security code received on your Google Authenticator App.
Two-Factor Authentication safeguards your account from any data breach.
