For IT leaders
MFA coverage is the first thing every cyber-insurance and audit conversation asks about; gaps are expensive to defend.
Why IT teams care
Where this shows up at the team level
- Cyber insurance and most compliance frameworks require MFA on admin and remote access.
- Phishing-resistant MFA (FIDO2 / passkeys) is the next step many teams have not finished.
- Help desk and identity teams need clean enrollment, recovery, and break-glass processes.
In production
Where teams encounter it
- Microsoft Entra / Okta / Google conditional access policies
- VPN and Zero Trust gateways enforcing MFA on remote access
- Privileged access management (PAM) tools for admins
How it works
How MFA actually works
- 01After a successful password (or passwordless first factor), the user must present a second factor: TOTP code, push approval, hardware key, or biometric.
- 02Modern deployments push toward phishing-resistant MFA (FIDO2 / WebAuthn) because SMS and basic push approval can be bypassed.
- 03Conditional access policies decide when MFA is required (e.g. unfamiliar location, risky sign-in, sensitive app).
- 04Recovery flows must be designed carefully so attackers cannot reset MFA without verification.
In practice
Common team use cases
- Protecting administrator and remote-access logins
- Stepping up authentication when risk signals fire
- Replacing passwords entirely with passkeys
