When I open a connection to a remote server, using for example sshg3, and then open another connection as same user to the same remote server I do not need to authenticate. The connection seems to go through without asking for my password. What is going on?

I don't have any other authentication methods configured other than password (not using public keys).

ssh-broker-g3 is reusing the connection to the server. As there is already an open, authenticated and encrypted connection to the server, there is no need for a costly key-exchange operation or authentication.

SSH Connection Protocol handles multiplexing of channels so that they don't interfere each other.

You can see the current connections and their channels with

% ssh-broker-ctl list-connections --show-channels
