Establish IAM users and groups while granting them specific permissions through the use of policies and roles to control access to designated services and resources. You can allow a trusted HUAWEI CLOUD account or a cloud service to access your resources according to the permissions that have been assigned. Furthermore, create a trust relationship between your current identity system and HUAWEI CLOUD by implementing a SAML-based or OpenID Connect-based identity provider, or by utilizing a custom identity broker. This setup enables users within your organization to log in to HUAWEI CLOUD seamlessly via single sign-on (SSO). Additionally, you may require IAM users to undergo identity verification each time they log in or engage in significant activities to enhance security. The IAM service empowers you to create users and authorize secure resource access via their unique usernames and passwords, while also enabling the authorization of another HUAWEI CLOUD account or a cloud service to utilize your resources under the defined permissions. In doing so, you ensure a robust and secure management of access to your cloud resources.
