Passwords are easy to steal, reuse and phish. In cloud-first environments, one compromised password can open email, files, business applications and remote access. Multi-factor authentication reduces that risk by requiring a second proof of identity.
Why passwords are not enough
Credential leaks, phishing kits and password spraying make single-factor login fragile. Even strong passwords can be captured if a user is tricked into entering them on a fake page.
What MFA adds
MFA combines something the user knows with something they have or are. This can be an authenticator app, a push approval, a hardware security key or biometric verification.
Choosing the right method
Hardware security keys offer strong protection against phishing. Authenticator apps are a practical default for many teams. SMS should be used only when stronger methods are not available.
Deployment without friction
Successful MFA projects include user communication, enrolment support, recovery procedures and clear exception handling. Conditional access can reduce prompts while keeping risky sessions protected.
