Understanding Two-Factor Authentication for Office 365
A second layer of login security is one of the cheapest, most effective protections available today.
Two-factor authentication (2FA) requires a second piece of proof beyond your password — typically a code from a phone app or text message — before allowing a sign-in. Even if an attacker steals or guesses your password, they can't get into your account without that second factor.
Office 365 supports 2FA for business accounts, and turning it on is one of the highest-value security changes you can make this year. Given how often passwords are exposed in unrelated data breaches and reused across services, 2FA is quickly becoming a baseline expectation rather than an optional extra.
We recommend rolling it out to your most sensitive accounts first — anyone with access to financial systems, HR data, or administrative controls — before expanding it to your whole team.
