The visibility logic is incomplete for the new Keyboard_Interactive authentication mode. While the comment indicates it only requires username, the code doesn't explicitly set the visibility flags to false for this mode. This could result in unexpected form field visibility when Keyboard_Interactive is selected.

Consider adding explicit handling for when authModeAsNumber equals SshAuthMode.Keyboard_Interactive to ensure both showPasswordInput and showPrivateKeyInput are set to false.

Suggested change

	visibility.showPasswordInput = authModeAsNumber === SshAuthMode.Username_and_Password;
	visibility.showPrivateKeyInput = authModeAsNumber === SshAuthMode.Private_Key;
	// Reset all visibility flags before enabling those required for the selected auth mode
	visibility.showPasswordInput = false;
	visibility.showPrivateKeyInput = false;
	if (authModeAsNumber === SshAuthMode.Username_and_Password) {
	visibility.showPasswordInput = true;
	} else if (authModeAsNumber === SshAuthMode.Private_Key) {
	visibility.showPrivateKeyInput = true;
	}
