Connection profiles (.cyberduckprofile) describe specific connection settings for a hosting provider to make it easier to setup a connection to your provider. A connection profile installed adds a provider option in the protocol selection dropdown menu. Then create a new bookmark and only enter your credentials. Ready to connect!
Download and double click the connection profile file (.cyberduckprofile) to open and register the profile with Cyberduck and Mountain Duck or alternatively enable in Preferences → Profiles. Connection profiles are shared between Cyberduck, Cyberduck CLI and Mountain Duck.
Easily activate additional connection profiles not enabled by default in the Profiles tab in Cyberduck → Preferences. Refer to the documentation.
