The SSH configuration form only asked for a password after a failed Test Connection, so choosing Password showed nothing but a "Save password" checkbox. It now shows a Password row, or a Passphrase row for key pairs.
The typed secret is staged with the other settings changes: it is written on Apply / OK and discarded on Cancel or Reset, and Test Connection uses it without storing it. An emptied field leaves the stored secret alone. Deployment, run target and data source forms have their own secret inputs and are unchanged.
