Connecting to PixHawk with MAVLink SIGNING

Hello dear forum,

I would like to connect via USB to a pixhawk protected with SIGNING, without using the authenkey, in case I’ll forget the password in the future.

In the MAVLINK website the state that the USB connection is unaffected by SIGNING, but no matter what I do, I can’t seem to connect to the pixhawk, after removing the authenkey from the MP.

If you have any ideas what can I do to connect to a SIGNING protected pixhawk via USB, I’d love to hear them.

Thank you in advance!
