What is MFA?
MFA requires a second proof — an app prompt, hardware key or biometrics — besides the password. It blocks most account-takeover attacks against Microsoft 365.
Quick answer
Multi-factor authentication means logging in with something you know plus something you have or are. For Dubai businesses, turning on MFA for Microsoft 365 and VPN is the single highest-ROI security control we deploy.
Key takeaways
- Prefer app or FIDO2 keys over SMS
- Cover admins first, then every user
- Pair with Conditional Access

MFA is not optional in 2026
Insurers, Microsoft and most customer questionnaires assume MFA is on. We enable it in days as part of onboarding, with break-glass accounts documented.
