The HTTP Permissions-Policy header publickey-credentials-create directive controls whether the current document is allowed to use the Web Authentication API to create new WebAuthn credentials, i.e., via navigator.credentials.create({publicKey}).
Specifically, where a defined policy blocks use of this feature, the Promise returned by navigator.credentials.create({publicKey}) will reject with a NotAllowedError DOMException. If the method is called cross-origin, the Promise will also reject with a NotAllowedError if the feature is granted by allow= on an iframe and the frame does not also have Transient activation.
Permissions-Policy: publickey-credentials-create=<allowlist>;<allowlist>A list of origins for which permission is granted to use the feature. See Permissions-Policy > Syntax for more details.
The default allowlist for publickey-credentials-create is self.
