According to the NitroKey 3 FAQ on Azure Entra ID and the Certificates page it appears NitroKey 3 does not have any attestation.
Are there any plans to provide attestation for NitroKey 3?
Background: I tried to use my NitroKey 3C for the new swiss government authentication platform (agov.ch) and it fails with the error “Attestation not trusted” - although they only specify that FIDO2/WebAuthn is required.
Also it would be great if there were at some note on the product page for future buyers regarding the attestation status of NitroKey 3. Because I get the feeling more and more platforms are requiring attestation
