Multi-factor authentication is an authentication method that uses two or more verification methods to access an account.
For example, instead of simply asking for a username or password, multi-factor authentication asks for additional information:
An additional one-time password that the website’s authentication servers send to your phone or email address.
Answers to personal security questions.
A fingerprint or other biometric information, such as voice data or facial recognition.
Multi-factor authentication reduces the likelihood of a cyberattack being successful. To protect your online accounts, it is recommended to use multi-factor authentication whenever possible.
You can also use third-party authenticator apps such as Google Authenticator or Authy to stay safe online.
