Require Password from remote?

I'm in the process of setting a an OFTP2 connection to a partner.
The OFTP version we use is the open source version 1.0 build 39
from 2019-01-04.
From the partner I got a password which I successfully entered in
the partner dialog in the "Routing" tab: "Password to send to this
partner (SSIDPSWD)". Now the partner requests a password from
me and I do not find any way to enter a local password that should be
required from the partner. Is this possible? We're using only SSL
on port 6619.
