Walter shows you how to
recover access to an EC2 instance
if you lost your SSH key pair


I've lost my SSH private key and am locked out of my Amazon Elastic Compute Cloud (Amazon EC2) Linux instance. How can I recover access?

Warning: Do not perform this procedure if your EC2 instance is an instance store-backed instance. This recovery procedure requires a stop and start of your instance, which means that data on instance store volumes will be lost. For more information, see Determining the Root Device Type of Your Instance.

To recover access to your Linux instance using AWS Systems Manager (SSM) automation, run the AWSSupport-ResetAccess Automation automation document. For more information, see Reset Passwords and SSH Keys on Amazon EC2 Instances.

Or, to manually recover access to your Linux instance, create a new key pair to replace the lost key pair. For more information, see Connecting to Your Linux Instance If You Lose Your Private Key.
