Multi-Factor Authentication and Account Recovery

Strengthen authentication beyond passwords with MFA, and design secure account recovery flows that do not become a backdoor around your protections.

Beyond the Password

Strong access control and good session management still rest on one assumption: the user is who they claim. Passwords alone are weak. Multi-factor authentication adds layers so a stolen password is not enough.

The Three Factors

Authentication factors fall into categories:

  • Something you know — password, PIN
  • Something you have — phone, hardware key
  • Something you are — fingerprint, face

MFA combines two or more different categories.
