displayName

A user visible name for the identifier. For app types it will contain the localized name of the app. For URL types it will contain the host name of the URL if it contains a valid host. For URL type identifiers that do not contain a valid host and for domain type identifiers, this will be equal to identifier. This property is meant only as a best effort suggestion for display purposes. It is not used by the system to identify the service or suggest a credential for AutoFill.
