You can either use:

Default administrator's credentials

The default credentials for the administrator are:

  • Login: admin
  • Password: admin


Forgot your admin's password?


See the following tutorial to reset the admin's password to admin.

Locked yourself out?


See the following tutorial to help you get back in.

Change your password

Log in and click on your name (the top right of the screen).

The way security is implemented in Sonar is pretty standard. It is possible to create as many users and groups of users as required in the system. The users can then be attached (or not) to (multiple) groups. Groups and / or Users are then given (multiple) roles. The roles give access to the various services and functionality in Sonar.


There are 4 roles in Sonar, 1 is global, the 3 other are attached to a project :

  • Global Administrators : Ability to perform all administration functions for the instance: global configuration, personalization of TimeMachine and Home Page



    Be careful not to suppress the latest administrator, otherwise, you will be locked out

  • Project Administrators : Ability to perform administration functions for a project by accessing its settings
  • Project Users : Ability to navigate through every service of a project, except viewing source code and settings
  • Project Code viewers : Ability to view source code of a project

Default project roles

It is possible to configure the system so that when a new project is created, the project roles are automatically assigned to users or / and groups

Special groups

Two groups have a special status in Sonar :

  • "Anyone" is a group that exists in the system, but that cannot be managed. Every user belongs to this group
  • "sonar-users", when it exists, is the group to which user are automatically added. It is not possible to configure the name of this default group.

Global settings

Force user authentication : this is really the first question that should be answered where putting some security in place in Sonar. Can anybody browse the instance or do you need to be authenticated.

Allow users to sign up online : this means that anybody can access a form to create himself an account in the system. To be noted that after filling the form, the users should log in.

External password management : this should be used to indicate that an external system is used for authentication

Delegate Authentication and Authorization to an External System

To do, you should install and configure the Sonar LDAP Plugin.
