By default there is only 1 user created during the installation process of BVQ (default name: bvq, role: root). You can modify the user & password in the repository installer within the DB access screen.

This user afterwards is used by the BVQ services & UIs to connect to the database. Whenever you change the password of the user remeber to change it in the other BVQ modules (GUI DB connection profile, etc.)
