Here’s how to search for an IAM user in AWS by filtering their access key.
aws iam list-users --query 'Users[?UserId==`AIDAxxxxxxxxxxxxxxxxx`]' \ --profile your-profile |
The results only returns one user with that UserID.
[ { "Path": "/", "UserName": "your-username", "UserId": "AIDAxxxxxxxxxxxxxxxxx", "Arn": "arn:aws:iam::xxxxxxxxxxxx:user/sa-lucidchart", "CreateDate": "2019-04-15T15:53:18+00:00" } ] |
