AWS_IAM_45
Inline policies are policies that are embedded directly into a single user, group, or role. It is recommend to use managed policies instead of inline policies. Managed policies provide reusability, central change management, versioning and more capabilities.
In the IAM console, select Users from the navigation pane, and then select Permissions. Remove any policies attached directly to the user (these are inline policies), and replace them with equivalent managed policies (in the Policies page) that are assigned to users, groups or roles.
