I have a QGIS project, based on data from a PostgreSQL database. In this database I create an extra user, with limited rights. I want to give this project to other users, but I don't want that they have to enter the login data everytime they open the project. Therefore I store the connection to the database and the login data in the qgis_global_settings file and replace it on the PC of every project user. It works fine and they can use the database, but if they want to open the project, the have to enter a master password. I never set any master password.
Where is the master password in QGIS stored?
Is there any file that I can give to the user, maybe in the qgis_global_settings or the qgis3.ini?
I do not want the user to have to enter any login data.
