Choose MFA by risk tier, not by checkbox coverage

The guide compares common factors by phishing resistance, recovery weakness, support impact, and fit for administrators, finance, executives, and general users.

Sample decisions

Use passkeys or FIDO2 security keys for users with administrative, financial, or sensitive-data access.
Treat authenticator apps as a workable workforce baseline, not the final answer for privileged roles.
Review help desk recovery and enrollment controls before calling any MFA rollout complete.

Common mistakes

Treating SMS, push, TOTP, security keys, and passkeys as equivalent because all count as MFA.
Rolling out better factors without backup-factor and lost-device procedures.
Ignoring support desk reset workflows that can bypass the primary authenticator.

SMS OTP is easy to deploy but weak against SIM swap and real-time phishing.
Authenticator app TOTP improves baseline security but remains phishable.
Push MFA needs number matching and fatigue controls.
FIDO2 security keys provide strong phishing resistance for high-risk users.
Passkeys can improve usability and phishing resistance when recovery controls are mature.
Recovery workflows, enrollment controls, and administrator exceptions often decide real-world strength.
