When running the Hello app, we tell you to put your Golioth credentials in the prj.conf file. This is not a great practice as it’s really easy to accidentally commit your credentials to a git repository. I instead like to use a separate credentials.conf file which I then add to my .gitignore file.
# credentials.conf CONFIG_GOLIOTH_SYSTEM_CLIENT_PSK_ID="my-psk-id" CONFIG_GOLIOTH_SYSTEM_CLIENT_PSK="my-psk"
Then include this file at build time:
west build -b esp32 . -D OVERLAY_CONFIG=credentials.conf -p
Just remember to add credenditals.conf to your .gitignore file:
build*/ .vscode credentials.conf
You can see a working example of this in the magtag-demo repository.
