Dual Authentication. SFTP reciever adapter

Hi.

I have a case where I have to use private key and password.

My question is. How do I set up the Additional parameters in Advanced Mode.

This is a clip from note 2028233.

auth.method.privatekey - A boolean, which enables two factor authentication

privatekey.view - The view name of the Private key

privatekey.entry - The private key name

Privatekey.view and privatekey.entry I think I i know, but not  auth.method.privatekey.

Regards

Per Arne
