Compromising multiple authentication factors presents a significant challenge for attackers. Even if an attacker manages to learn the user's password, it is useless without also having possession of the trusted device.

Users can choose the methods they prefer. To learn more, see What is %BRAND_AZURE_SHORT% Multi-Factor Authentication? and How %BRAND_AZURE_SHORT% Multi-Factor Authentication works.
