Here is the complete, single-file index.html. It contains the HTML, CSS, and the OmegaID JS engine all in one package. It requires zero build steps, zero NPM packages, and is entirely client-side. https://id.omega-mesh.org/ OmegaID // Terminal Generate ID Authenticate Encryption Passphrase (do not forget this) Generate & Download JSON > System initialized. Ready. How the cross-service flow works out of the box: If you build a new service (e.g., your Mesh dashboard or an edge gateway router), you don't need to rebuild auth screens. Your service just bounces the user to your tunnel: [https://id.omega-mesh.org/?action=auth&challenge=random_login_nonce_123&callba ck=https://your-new-service.org/verify](https://id.omega-mesh.org/?action=auth& challenge=random_login_nonce_123&callback=https://your-new-service.org/verify) The index.html file detects those parameters on load. It automatically switches to the "Authenticate" tab, pre-fills the challenge, and prompts the user for their file and passphrase. As soon as the user clicks sign, the JS builds the signature and automatically redirects them back to [https://your-new-service.org/verify?omega_id=...&signature=](https://your-new- service.org/verify?omega_id=...&signature=)... to complete the loop.
