 ### Overview
 
-HawkBit Update Server username/password -> admin/admin as default login credentials. They can be overridden by the
-environment variables spring.security.user.name and spring.security.user.password which are defined in the corresponding
-default [application.properties](hawkbit-runtime/hawkbit-update-server/src/main/resources/application.properties).
+HawkBit Update Server default user has _admin/admin_ as default credentials. See below how the user can be changed.

 ### 2: Start hawkBit [update server](https://github.com/eclipse-hawkbit/hawkbit/tree/master/hawkbit-runtime/hawkbit-update-server) (Monolith)
 
 ```sh

-$ cd hawkbit-examples
-$ mvn clean install
+### 3: Change credentials
+As stated before the default user is _admin/admin_. It could be overridden by changing the [TenantAwareUserProperties](https://github.com/eclipse-hawkbit/hawkbit/blob/master/hawkbit-core/src/main/java/org/eclipse/hawkbit/tenancy/TenantAwareUserProperties.java) configuration using Spring ways. For instance, using a properties file like:
+```properties 
+# should remove the admin/admin user
+hawkbit.security.user.admin.tenant=#{null}
+hawkbit.security.user.admin.password=#{null}
+hawkbit.security.user.admin.roles=#{null}
+# should add a hawkbit/isAwesome! user
+hawkbit.security.user.hawkbit.tenant=DEFAULT
+hawkbit.security.user.hawkbit.password={noop}isAwesome!
+hawkbit.security.user.hawkbit.roles=TENANT_ADMIN
 ```
+which should remove the default _admin/admin_ user and add a hawkbit user _hawkbit_ with password _isAwesome!_ and a role _TENANT_ADMIN_.
