Creating an IAM User

If you are an administrator and have created multiple resources on the cloud platform, such as Elastic Cloud Servers (ECSs), Elastic Volume Service (EVS) disks, and Bare Metal Servers (BMSs), you can create IAM users and grant them permissions required to perform operations on specific resources. This way, you do not need to share the password of your account.

New IAM users do not have any permissions assigned by default. You can assign permissions to new users, or add them to one or more groups and grant permissions to these groups by referring to Assigning Permissions to a User Group so that the users can inherit the permissions of the groups. The users then can perform specific operations on cloud services as specified by the permissions.

The default user group admin has all permissions required to use all of the cloud resources. Users in this group can perform operations on all the resources, including but not limited to creating user groups and users, modifying permissions, and managing resources.

If you delete a user and then create a new user with the same name, you need to grant the required permissions to the new user again.

Procedure

  1. Log in to the IAM console as the administrator.
  2. Choose Users from the left navigation pane and click Create User in the upper right corner.
  3. Specify the user information on the Create User page. To create more users, click Add User. You can add a maximum of 10 users at a time.

    Table 1 User details

    Parameter

    Description

    Username

    This parameter is user-defined and cannot be the same as that of any other account or any IAM user in the account.

    Email Address

    This parameter is user-defined and cannot be the same as that of any other account or any IAM user in the account. It can be used to authenticate the IAM user and reset the password.

    Mobile Number

    This parameter is user-defined and cannot be the same as that of any other account or any IAM user in the account. It can be used to authenticate the IAM user and reset the password.

    External Identity ID

    Identity of an enterprise user in IAM user SSO. The value contains a maximum of 128 characters.

    This parameter must be specified if you want to configure identity federation via SAML for an IAM user.

  4. Specify Access Type.

    Table 2 Access types

    Access Type

    Description

    Programmatic access

    Allows users to access cloud services using development tools such as APIs, CLI, and SDKs.

    Management console access

    Allows users to access cloud services through the management console. A password is mandatory for login.

  5. Specify Credential Type.

    Table 3 Credential types

    Credential Type

    Description

    Access key

    After creating the user, you can download the access key (AK/SK) generated for the user.

    Each user can have a maximum of two access keys.

    Password

    Set now

    Set a password for the user and determine whether to require the user to reset the password at the first login.

    If you will use the IAM user by yourself, you are advised to select this option, enter a password, and deselect Require password reset at first login.

    Automatically generated

    The system automatically generates a login password for the user. After the user is created, you can download the EXCEL password file and provide the password to the user. The user can then use this password for login.

    This option is available only when you create a single user.

    Set by user

    A one-time login URL will be emailed to the user. The user can click on the link to log in to the console and set a password.

    If you do not use the IAM user by yourself, select this option and enter the email address and mobile number of the IAM user. The user can then set a password by clicking on the one-time login URL sent over email. The login URL is valid for seven days.

  6. Configure login protection. This parameter is available only when you have selected Management console access for Access Type.

  • IAM users created without being added to any groups do not have any permissions. The administrator can assign permissions to these IAM users on the IAM console. Then the users can use cloud resources based on the assigned permissions. For details, see Assigning Permissions to an IAM User.
  • Accounts and IAM users use different methods to log in. For details about IAM user login, see Logging In as an IAM User.
