Roles are a quick way of granting a set of privileges to a user, based on the work the user must carry out on the server. It is also possible to assign multiple roles to a user account or to assign privileges directly to an account without first assigning roles.
After you select a role for a user account, you will see the accumulated privileges in the Global Privileges panel. For example, if you select the role BackupAdmin, the privileges granted include EVENT, LOCK TABLES, SELECT, SHOW DATABASES. For a complete list of privileges, see Privileges Provided by MySQL

This role is not available for all default accounts, such asroot.
