IAM: Manage a specific tag

This example shows how you might create an identity-based policy that allows adding and removing the IAM tag with the tag key Department from IAM entities (users and roles). This policy does not limit the value of the Department tag. This policy grants the permissions necessary to complete this action programmatically from the AWS API or AWS CLI. To use this policy, replace the italicized placeholder text in the example policy with your own information. Then, follow the directions in create a policy or edit a policy.
