IAM Credentials Report
The IAM Credentials Report is a built-in AWS tool that provides information about users and user authentication in an AWS account. The report lists all users, their creation dates, and details about their authentication methods including passwords, access keys, and MFA devices, along with timestamps of when these credentials were last used. You can access this report through both the AWS Console and the AWS CLI, and that’s what I’ll show you in this CybrBit. This report is particularly useful for auditing user credentials and can help organizations transition from IAM users to AWS Identity Center.
