Description

This policy defines a list of allowed HTTPS origins for remote desktop client applications that initiate WebAuthn API requests from a browsing session on a remote host. Origins specified in this policy can request WebAuthn authentication for Relying Party IDs (RP IDs) they wouldn't typically be authorized to claim. Only HTTPS origins are supported. Wildcards aren't permitted. Entries that don't meet these requirements will be ignored.
