![]() If the user does not exist, or currently authenticates using a password, a Selector Action is shown. Login therefore requires only a couple of clicks, and is both user friendly and secure. Proof of ownership of a private key is then sent to the authorization server. This involves a simple action such as inserting a Yubikey and tapping it. If the user exists and has any WebAuthn devices registered, they are prompted to provide a WebAuthn credential. This is then remembered in an HTTP-only cookie, and auto-filled for subsequent logins: It starts by presenting a Username Authenticator, which identifies users before authentication, by collecting the user's email. The authentication workflow is implemented using Authenticators and Authentication Actions.

This tutorial will cover an internet application scenario, though the techniques used could be applied to many other use cases. This tutorial shows how to implement the correct behavior, using the Curity Identity Server. Instead you need a smarter design that ensures data integrity, and therefore business continuity, for all users. A first attempt to support both password and WebAuthn logins might involve simply presenting an authentication selection screen:īy default though, this would create a duplicate user account for any existing user who upgraded to use WebAuthn logins. Using WebAuthn is one way to enable this, with both strong security and also great usability. These days there are better options for authenticating users, and many users will expect a passwordless experience. This is problematic from both a security and user experience viewpoint, since passwords are both reused and forgotten. In the past, internet users have often had to create a new username and password for every online application they use.
