Note：

This document describes the access management feature of SMS. For more information on access management for other Tencent Cloud services, please see CAM-Enabled Products.

SMS access management essentially binds sub-accounts to policies or grants policies to sub-accounts. You can use preset policies directly in the console to implement some simple authorization operations. For more complicated authorization operations, please see Custom Policies.

Currently, SMS provides the following preset policies:
