Hello!
I flashed my ESP32 S3 with web ESP32 Flasher - www.picokeys.com/esp32-flasher/

but right now there is: AAGUID: 00000000-0000-0000-0000-000000000000

It is possible set some random AAGUID if just using WEB esp32-flasher and Pico Commissioner on Windows PC ?

AAGUID is set at eb857df3e1/src/fido/cbor.c (L47)

If you see all zeros might be because of your browser.

This is how it works.
When Attestation is set to None, AAGUID is replaced by all zeros (more info https://www.w3.org/TR/webauthn-2/#sctn-createCredential).
If you want to see the AAGUID, go to webauthn.io and select Attestation -> Direct.
