# UpdateTrustAnchor
<a name="API_UpdateTrustAnchor"></a>

Updates a trust anchor. You establish trust between IAM Roles Anywhere and your certificate authority (CA) by configuring a trust anchor. You can define a trust anchor as a reference to an AWS Private Certificate Authority (AWS Private CA) or by uploading a CA certificate. Your AWS workloads can authenticate with the trust anchor using certificates issued by the CA in exchange for temporary AWS credentials.

 **Required permissions: ** `rolesanywhere:UpdateTrustAnchor`.
