SecurityΒΆ
Yamcs includes a security subsystem which allows authenticating and authorizing users. Authentication is the act of identifying the user, whereas authorization involves determining what privileges this user has.
If security is disabled (the default if unconfigured), Yamcs will not require authentication and associate all API access with an imaginary guest user with superuser rights.
If security is enabled, users may be assigned privileges that determine what actions they can perform. Yamcs distinguishes between system privileges and object privileges.
Note
Starting with Yamcs v5.13.6, Yamcs will no longer automatically create an admin user.
If you are thinking about enabling security, you can yourself choose whether you want to create an internal user with superuser rights in the Admin Area. Or alternatively, such a user could come from an external identity provider through one of the AuthModules.
