To retrieve information about when the specified access key was last used

The following example retrieves information about when the access key ABCDEXAMPLE was last used.

aws iam get-access-key-last-used \
    --access-key-id ABCDEXAMPLE

Output:

{
    "UserName":  "Bob",
    "AccessKeyLastUsed": {
        "Region": "us-east-1",
        "ServiceName": "iam",
        "LastUsedDate": "2015-06-16T22:45:00Z"
    }
}
