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.
