Listing Users with aws iam list-users

When you want to know who has access to the account, use aws iam list-users. It lists every IAM user.

The syntax is aws iam list-users.

Running it returns JSON with each user's name, ID, ARN and creation date.

A common stumble is leaving the accounts of departed team members in place. Unused credentials are a standing security risk.

In real work, it is part of routine access audits — checking who exists and whether they still need to.
