WebAuthn

Casdoor supports WebAuthn so users can sign in with built-in authenticators (fingerprint, face, Windows Hello) or security keys (e.g. YubiKey) instead of (or in addition to) a password.

What is WebAuthn?​

WebAuthn (Web Authentication API) is a W3C/FIDO standard that uses public-key cryptography for registration and sign-in. The server stores a public key; the private key stays on the user’s device. Sign-in works by proving possession of the private key (e.g. via biometrics or a security key). Credentials are bound to the user, the authenticator, and the site origin.

For more detail: webauthn.guide.

Enable WebAuthn in Casdoor​

Step 0: Configuration​

  1. In conf/app.conf, set origin to the exact URL of your Casdoor site:

    origin = "http://localhost:8000"

    WebAuthn requires HTTPS in production; localhost is allowed for development.

  2. As an admin, open the application edit page and turn on Enable WebAuthn signin (off by default).

Step 1: Register a credential​

Go to My Account. Use Add WebAuthn Credential and follow your device’s prompt to register a new credential. You can delete credentials from the list.

Step 2: Sign in with WebAuthn​

Sign out, then on the login page select the WebAuthn method, enter your username, and click sign in. Complete the authenticator step (e.g. fingerprint or Windows Hello).
