ZBT 3526 Upgraded to new Firmware: Password (SOLVED)

Hi,
just in case someone gets stuck like I did, when I upgraded my pre-release self compiled 18.06.0 to the latest release, for some reason the password was set. Found ´1234´ worked, which might save someone from hair removal!
btw, I had difficulties talking via SSH to the upgraded WG3526 router. It seems modern browsers are too smart sometimes. Worth keeping an old system around....

So far, all seems good & I wish to thank the developers for all the hard work.
