As a SonarQube user you have your own space where you can see the things that are relevant to you:
It gives you a summary of:
- your Groups
- your SCM accounts
If your instance is not using a 3rd party authentication mechanism such as LDAP or an OAuth provider (GitHub, Google Account, ...), you can change your password from here. Additionally, you can also manage your own authentication tokens.
You can create as many Tokens as you want. Once a Token is created, you can use it to perform analysis on a project where you have the Execute Analysis permission.
