Multi-factor authentication adds another proof of identity beyond a password. That matters because passwords can be reused, guessed, phished or exposed in breaches.
What changes as the office grows
For a small office, the priority should be accounts that can unlock other systems: Microsoft 365 administrators, email, accounting, remote-access tools, password managers and backup platforms. Start there before trying to secure every possible application at once.
What better management looks like
MFA is strongest when it is paired with good account hygiene. Each employee should have an individual account, former employees should be removed promptly, privileged administrator accounts should be separate from everyday accounts, and shared passwords should be avoided.
What to do next
Security controls can feel inconvenient when they are introduced without a plan. Good implementation balances stronger authentication with clear enrollment instructions, recovery methods and documented ownership.
