CLI

AWS CLI

To change an IAM user's name

The following update-user command changes the name of the IAM user Bob to Robert.

aws iam update-user \
    --user-name Bob \
    --new-user-name Robert

This command produces no output.

For more information, see Renaming an IAM user group in the AWS IAM User Guide.

PowerShell

Tools for PowerShell

Example 1: This example renames the IAM user Bob to Robert.

Update-IAMUser -UserName Bob -NewUserName Robert

Example 2: This example changes the path of the IAM User Bob to /Org1/Org2/, which effectively changes the ARN for the user to arn:aws:iam::123456789012:user/Org1/Org2/bob.

Update-IAMUser -UserName Bob -NewPath /Org1/Org2/
