Summary
What is 2FA?
Two-factor authentication (2FA) offers a second layer of security to help protect an account from brute force, phishing, and social engineering attacks.
2FA requires an extra step for a user to prove their identity, which reduces the chance of a bad actor gaining access to their account or data. And since notifications are sent to verify the initial authentication via username and passwords, it also gives users and business the ability to monitor for potential indicators of a compromise.
