What Is Multi-Factor Authentication (MFA)?
Multi-factor authentication adds additional layers of security to your accounts. Now, even if a criminal knows your password, they won’t be able to access your account.
The additional authentication comes in various forms such as an SMS, a voice call, one-time passcode, or push notification on a trusted device. It can also be biometric data such as a fingerprint scan.
MFA used to be referred to as 2FA (two-factor authentication), but now the phrase multi-factor authentication is preferred for any login system requiring two or more identity credentials.
