Furthermore, Windows 11 promotes the use of multi-factor authentication (MFA) through its integration with Azure AD, significantly raising the security bar against unauthorized access. MFA requires users to provide two or more verification factors to gain access to resources, which is a step up from the traditional single-password method. This integration means that users might be prompted for a fingerprint, facial recognition, or a unique pin — in addition to their password — when accessing sensitive company resources, thus providing a robust layer of protection.

Microsoft has also paid considerable attention to making identity management more user-friendly in Windows 11. The operating system includes features like single sign-on (SSO), which reduces the need for users to repeatedly log in when accessing various services and applications that are connected to Azure AD. This not only enhances the user experience but also simplifies access management for IT administrators.

Passwordless authentication is another forward-thinking feature embraced in Windows 11. This approach leverages Windows Hello for Business, a feature that allows users to unlock their devices using biometric data or a PIN.
