Passwords alone are no longer enough to protect business accounts. Criminals can steal passwords through phishing, malware, password reuse, or data breaches.
Multifactor authentication, often called MFA, adds another step when a user signs in. That second step may be a phone app approval, a security key, or another trusted method. Even if a criminal learns the password, they still need the second factor.
MFA is especially important for Microsoft 365, banking, remote access, cloud applications, and administrative accounts. It is one of the simplest ways to stop many common account takeover attempts.
Businesses should avoid weak MFA methods when stronger choices are available. Push approvals that show number matching, authenticator apps, and security keys are generally safer than relying only on text messages.
The goal is not to make work difficult. The goal is to make a stolen password less useful to an attacker. A few extra seconds during sign-in can prevent hours or days of recovery work after an account compromise.
