## Read database passwords

By default, access to each service database is assigned to a user with randomly generated passwords. For example, to read the campaign service database password, execute the following command:

```bash
kubectl get secret database-user-credentials -o go-template='{{ .data.campaign | base64decode }}'
```

The username for the campaign service can be found in the configuration file under each service section. To read the username for the campaign service set during the installation, launch the following command:

```bash
helm get values akamas --all --output json | jq '.campaign.database.user'
```

You can connect to the `campaign_service` database with the user and password above.

If you want to show all the passwords, execute this command:

```bash
kubectl get secret database-user-credentials -o go-template='{{range $k,$v := .data}} {{printf "%s: %s\n" $k ( $v |base64decode ) }}{{end}}'
```
