An external auditor requests a list of all IAM users and the status of their credentials and access keys. What is the easiest method to supply this information?

The IAM credential report is the easiest and most comprehensive method because it provides a detailed list of all IAM users in your account and the status of their various credentials, including passwords, access keys, MFA devices, and last used dates. This report is specifically designed for auditing purposes. Creating an IAM user for the auditor with administrator permissions is a significant security risk and unnecessary. Screenshots are inefficient, prone to errors, and do not provide a comprehensive, structured report. The AWS Trusted Advisor report focuses on cost optimization, security, fault tolerance, performance, and service limits, not detailed IAM user credential status.
