Enable passwordless security key sign in (preview)

For enterprises that use passwords today and have a shared PC environment, security keys provide a seamless way for workers to authenticate without entering a username or password. Security keys provide improved productivity for workers, and have better security.

This document focuses on enabling security key based passwordless authentication. At the end of this article, you will be able to sign in to web-based applications with your Azure AD account using a FIDO2 security key.

FIDO2 security keys are a public preview feature of Azure Active Directory. For more information about previews, see Supplemental Terms of Use for Microsoft Azure Previews


To use security keys for logging in to web apps and services, you must have a browser that supports the WebAuthN protocol. These include Microsoft Edge, Chrome, Firefox, and Safari.

Prepare devices for preview

Devices that you will be piloting with must be running Windows 10 version 1809 or higher. The best experience is on Windows 10 version 1903 or higher.
