<p>Generates a report that includes details about when an IAM resource (user, group, role, or policy) was last used in an attempt to access Amazon Web Services services. Recent activity usually appears within four hours. IAM reports activity for at least the last 400 days, or less if your Region began supporting this feature within the last year. For more information, see <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_access-advisor.html#access-advisor_tracking-period">Regions where data is tracked</a>.</p> <important> <p>The service last accessed data includes all attempts to access an Amazon Web Services API, not just the successful ones. This includes all attempts that were made using the Amazon Web Services Management Console, the Amazon Web Services API through any of the SDKs, or any of the command line tools. An unexpected entry in the service last accessed data does not mean that your account has been compromised, because the request might have been denied. Refer to your CloudTrail logs as the authoritative source for information about all API calls and whether they were successful or denied access.
