By default there is only 1 user created during the installation process of BVQ. 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.)

Change the password of an existing user

1. Establish a connection to MongoDB via mongo CLI (use CMD or PowerShell)

mongo --authenticationDatabase admin -u bvq -p P@ssw0rd

(default location of binaries = C:\Program Files\SVA\BVQ\bvq-mongodb\bin, put in PATH variable to access from outside the directory
change username -u and password -p to your credentials)

1. The user information is configured globally for the entire MongoDB in the admin DB, so you have to switch to this DB.
   List existing dbs with show dbs command

   PS C:\Users\fschenke> mongo --authenticationDatabase admin -u bvq -p P@ssw0rd
   MongoDB shell version v3.4.4
   connecting to: mongodb://127.0.0.1:27017
   MongoDB server version: 3.4.4
   > show dbs
   admin       0.000GB
   bvq         0.401GB
   local       0.000GB

2. Mit dem Befehl use admin zur admin DB wechseln:

   > use admin
   switched to db admin

3. Über das Kommando db.changeUserPassword() kann das Passwort des Users geändert werden

   db.changeUserPassword("bvq", "NEW_PASSWORD")

   In diesem Beispiel wird das Passwort des Users bvq auf NEW_PASSWORD geändert.

4. Nach Ausführung des Befehls wird das PW geändert. Eine Anmeldung ist dann nur mit neuem Passwort möglich.

   PS C:\Users\fschenke> mongo --authenticationDatabase admin -u bvq -p P@ssw0rd
   MongoDB shell version v3.4.4
   connecting to: mongodb://127.0.0.1:27017
