My new setup send data to flightaware.com/adsb/stats/site/31297 ( Unclaimed)
Where i can change user?
I use PiAware 3.1.0

Best Regards

Have you already tried to claim your PiAware by going to the claim page? flightaware.com/adsb/piaware/claim

How ?
On rpi i have only console mode, no desktop.
When i type:
pi@dom:~ $ sudo piaware-config -user tresor -password
piaware-config : piaware-config -help|-start|-stop|-restart|-status|-showall|-show ?key?|?key value?

Software dont have this option.

Sorry, there appears to be a bug with the PiAware claim page. We’re looking into it now.

We fixed an issue with the Claim page that may have been the problem here. Please go back to flightaware.com/adsb/piaware/claim from the same network to which the PiAware is connected. This should complete the claim process.
