Try to get a simplified input of SSID and password to allow a prebuilt binary

Can you try this: https://docs.platformio.org/en/latest/projectconf/section_env_build.html

[env:string_defines]
build_flags =
  -DHELLO="World!"
  '-DWIFI_PASS="My password"'
  ; Password with special chars: My pass'word
  -DWIFI_PASS=\"My\ pass\'word\"

And probably in code

#ifndef variable then assign default value

Other option is to have USER_CONFIG file that users can update. Anyone who forks repo and edits this file in github would have firmware artifact built by actions.
