+// Access keys consist of two parts: an access key ID (for example, AKIAIOSFODNN7EXAMPLE)
+// and a secret access key (for example, wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY).
+// For more information about access keys, see Managing Access Keys for IAM
+// Users (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_access-keys.html)
+// in the IAM User Guide.
+//
+// When you pass an access key ID to this operation, it returns the ID of the
+// AWS account to which the keys belong. Access key IDs beginning with AKIA
+// are long-term credentials for an IAM user or the AWS account root user. Access
+// key IDs beginning with ASIA are temporary credentials that are created using
+// STS operations. If the account in the response belongs to you, you can sign
+// in as the root user and review your root user access keys. Then, you can
+// pull a credentials report (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_getting-report)
+// to learn which IAM user owns the keys. To learn who requested the temporary
+// credentials for an ASIA access key, view the STS events in your CloudTrail
+// logs (https://docs.aws.amazon.com/IAM/latest/UserGuide/cloudtrail-integration).
+//
+// This operation does not indicate the state of the access key. The key might
+// be active, inactive, or deleted. Active keys might not have permissions to
+// perform an operation. Providing a deleted keys might return an error that
+// the key doesn't exist.
