Definition
MFA (multi-factor authentication) requires two or more factor types—something you know (password), have (phone/app), or are (biometric)—before access. It reduces credential-stuffing impact when passwords leak.
Operational context for teams
Enterprise MFA programs often assume one human, one identity. Shared MFA extends governance to collective logins. Read the MFA for teams hub and shared MFA pillar.
Examples
- Workforce: Entra MFA on employee laptops.
- Operational: TOTP viewers for shared AWS billing login.
- Automation: API TOTP via RoboMFA for approved jobs.
