Identify your FIDO token based on its Attestation Certificate.
This site will show you the Attestation Certificate for your FIDO token. This Attestation is _not_ unique to your single token. It should be shared with at least 100,000 other devices. It should identify the manufacturer of the device and potentially model or family of models.
In order to get the certificate, you must say "Yes" when your browser prompt for "Allow this site to see your security key?"
The source code for this service is available at https://github.com/psanford/what-the-fido.
