Translations:Nastavení Outlook s MFA pro mobilní zařízení/1/en

Multi-Factor Authentication (MFA) adds an extra layer of security to your account. Instead of signing in with only your password, you must also verify your identity using another authentication method, such as a code generated on your mobile phone or biometric verification.

This significantly improves account security. Even if someone learns your password, they will not be able to access your account without your mobile device or another configured authentication method.
