Multi-factor authentication for teams
01

Passwords are not enough

Phished credentials are still the top path into business email and cloud accounts. Multi-factor authentication blocks most automated attacks even when a password is stolen.

02

Choose the right methods

Authenticator apps or passkeys beat SMS where possible. Admins should use stronger methods than standard users. Register backup options and document a break-glass process before enforcement day.

03

Roll out in phases

Pilot with IT and leadership, communicate clearly, then enforce tenant-wide in Microsoft 365 or your identity provider. Pair MFA with conditional access so company data stays off unmanaged devices.
