When using the Sen2Agri Distribution Installer and following all steps, the final message of the installer, as well as the user manual mentions to modify the SciHub & USGData credentials inside /usr/share/sen2agri/sen2agri-services/config/services.properties
However, neither are the keys available or anywhere documented, that need to be set. I was able to find the corresponding keys only by watching a youtube video about an installation procedure of sen2agri: https://www.youtube.com/watch?v=W4z6t1pUWnU
The corresponding keys should be pre-populated by the installation
