Thetis Hardware Security Key Tester
This local page uses the browser WebAuthn API to test a FIDO2/U2F-style hardware key. First register the key, then authenticate with the same key. Your credential ID is stored only in this browser's localStorage.
1. Insert key
Plug in your Thetis key. Use the browser where you want to test it.
2. Register
Create a test credential scoped to this local site.
3. Authenticate
Touch the key when prompted. Success means the browser got a signed assertion.
Run from http://localhost or HTTPS. WebAuthn will usually fail from plain http:// on a normal domain.
