# Using service-linked roles
<a name="using-service-linked-roles-intro"></a>

AWS Support and AWS Trusted Advisor use AWS Identity and Access Management (IAM)[ service-linked roles](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_terms-and-concepts.html#iam-term-service-linked-role). A service-linked role is a unique IAM role that is linked directly to Support and Trusted Advisor. In each case, the service-linked role is a predefined role. This role includes all the permissions that Support or Trusted Advisor require to call other AWS services on your behalf. The following topics explain what service-linked roles do and how to work with them in Support and Trusted Advisor.
