Does Entra ID have the capability to conceal authentication information during the authentication process?

Question

• Do Entra ID authentication processes, from MFA to single login, conceal authentication information during the authentication process?
• Does Entra ID have the capacity for password less authentication on Windows/Linux servers? Can a user be authenticated without a password, e.g. by using an authentication app/FIDO 2?

Thank you!

Hello Ava,

Entra ID's authentication process does provide the ability to hide authentication information. During multi-factor authentication (MFA) and single sign-on (SSO), authentication information such as passwords are not displayed or transmitted to ensure security.

Additionally, Entra ID supports passwordless authentication on Windows and Linux servers. This can be achieved by using methods such as Windows Hello for Business, the Microsoft Authenticator app, or a FIDO2 security key. These methods use a user-owned device (such as a phone or security key), biometrics, or knowledge (such as a PIN) to authenticate, eliminating the need for a password.

For example, Windows Hello for Business allows users to use biometrics or PINs to authenticate on Windows devices without requiring a password.

I hope the information above is helpful.
