Azure exclusively mandates the use of biometric authentication across all platforms, disregarding other methods for passwordless authentication.

Azure provides a flexible approach to passwordless authentication by supporting Windows Hello for Business, Microsoft Authenticator app, and FIDO2 security keys, thereby offering users a choice based on their device and preference.

Azure's passwordless authentication is limited to email-based verification codes, excluding more secure methods like biometrics or security keys.

Azure enables organizations to implement passwordless authentication across a wide range of devices and applications, including desktops, mobile devices, and web applications, significantly reducing the risk of phishing and credential stuffing attacks.
