Where possible, we recommend relying on temporary credentials instead of creating long-term
credentials such as access keys. However, for scenarios in which you need IAM users with
programmatic access and long-term credentials, we recommend that you rotate access keys.
Regularly rotating long-term credentials helps you familiarize yourself with the process. This is useful
in case you are ever in a situation where you must rotate credentials, such as when an employee
leaves your company. We recommend that you use IAM access last used information to rotate and
remove access keys safely.
