View User Access

Reviewing a user's recent service-level activity is very important before doing anything to it as it might delete an access from a principal (person or application), who is still using it.

Listing IAM Users

You can easily list the IAM users in your AWS account or in a specific IAM user group, and list all the user groups that a user is in, as described below.

To list all the users in the account

  1. AWS Management Console shows the users in your AWS account and you can choose Users from the navigation pane.
  2. AWS CLI: aws iam list-users.
  3. AWS API: ListUsers.

To list the users in a specific group

  1. You can select the User groups, their name, and the Users tab from the navigation pane of the AWS Management Console.
  2. AWS CLI: aws iam get-group.
  3. AWS API: GetGroup.

To list all the user groups that a user is in

  1. Select the Users, user name, and then, the Groups tab from the navigation pane of the AWS Management Console.
  2. AWS CLI: aws iam list-groups-for-user.
  3. AWS API: ListGroupsForUser.

Renaming an IAM User

As the console doesn't have an option for renaming or change a user's name or path, you must use the AWS CLI, Tools for Windows PowerShell, or AWS API and this change leads to the following things:
  1.  All the policies attached to the user stay with the user under the new name.
  2. The user stays in the same user groups under the new name.
  3.  The unique ID for the user remains the same. 
  4. All the resources or role policies that refers to the user as a principal will be automatically updated to use the new name or path. However, this doesn't happen when the user is referred as a resource, it should be done manually.

To rename a user

  1. AWS CLI: aws iam update-user.
  2. AWS API: UpdateUser.
