How to remove the Access key of a user in AWS

Introduction

An IAM user can have an Access Key and a Secret Key that can then be used to perform actions using the AWS CLI or programmatically. Each user is allowed to generate 2 sets of Access keys.

IAM user access keys that are not being used should be removed. Having numerous unused access keys extends the attack surface. These keys provide the same level of access as the user’s credentials, therefore, based on the permissions the user has been assigned, a key theft or leakage incident may result in a platform wide compromise.

In this article, we will provide a step by step walkthrough of how to remove the Access key for an IAM user in AWS.

Note: Before removing an Access key make sure it is not being used anywhere currently so that you can ensure that no application or access is broken due to key deletion.
