name : untag-resource.rst **To delete a tag from a KMS key** The following ``untag-resource`` example deletes the tag with the ``"Purpose"`` key from a customer managed KMS key. To specify the KMS key, use the ``key-id`` parameter. This example uses a key ID value, but you can use a key ID or key ARN in this command. Before running this command, replace the example key ID with a valid key ID from your AWS account. :: aws kms untag-resource \ --key-id 1234abcd-12ab-34cd-56ef-1234567890ab \ --tag-key 'Purpose' This command produces no output. To view the tags on an AWS KMS KMS key, use the ``list-resource-tags`` command. For more information about using tags in AWS KMS, see `Tagging keys <https://docs.aws.amazon.com/kms/latest/developerguide/tagging-keys.html>`__ in the *AWS Key Management Service Developer Guide*.
