Amazon EC2 key pairs are essential for accessing instances securely. However, over time, many users accumulate multiple key pairs, often resulting in confusion and potential security risks. Deleting unused key pairs not only streamlines access but also enhances security by reducing the attack surface. This article provides a detailed guide on how to identify and delete unused key pairs to maintain a clean and secure EC2 environment.

To delete unused key pairs, first, users can utilize the AWS Management Console or CLI. The article outlines step-by-step instructions on how to navigate the console, check existing key pairs, and identify which ones are no longer in use. Additionally, it emphasizes the importance of documenting any deleted key pairs to avoid losing access to important instances in the future.

The guide also highlights some best practices for managing key pairs, such as regularly reviewing and rotating keys, and employing IAM roles wherever possible. By following these practices, DevOps professionals can ensure a more efficient and secure infrastructure. The proactive management of key pairs reflects broader DevOps principles, promoting automation and security as core tenets of infrastructure management.
