    u2flib-server-demo

    A simple self-contained demo server supporting multiple devices per user. The central part is the Resource class.

    1. Clone

    git clone https://github.com/Yubico/java-u2flib-server.git

    2. Run

    ./gradlew run

    3. Try it out

    Then point a U2F compatible web browser to https://localhost:8443/assets/registerIndex.html.

    Note
    		 Since U2F requires a HTTPS connection, this demo server uses a dummy certificate. This will cause your browser to show a warning, which it is safe to bypass.

    Troubleshooting

    Q&A

    1. Why do I get error code 2?

      You are accessing the server using a URL that does not match the server’s App ID. The App ID is set to https://localhost:8443 by default, but you can change this in the Resource class.
