Replace username with your user name, such as ec2-user. You can enter the default user name, or enter a custom user name, if one was previously set up for the instance. For a list of default user names, see General Prerequisites for Connecting to Your Instance.

Resolution 1. Create a new key pair. Open the Amazon EC2 console. Stop your instance. Choose Actions, Instance Settings, and then choose View/Change User Data. Copy the following script into the View/Change User Data dialog box: 6. If you create your own key pair using the command line, follow the recommendations at create-key-pair or New-EC2KeyPair Cmdlet for key type and bit length. If you create your own key pair using a third-party tool, be sure that your key matches the guidelines at Importing Your Own Public Key to Amazon EC2.

  • May 12, 2017  DOWNLOAD YOUR EC2 KEY PAIR FILE. If you have not already downloaded (or cannot locate) your key pair (i.e mykeypair.pem) you will need to create a new EC2 instance and download a new one. A key pair consists of a public key that AWS stores and a private key file that you store (downloaded as PEM file).
  • In AWS, when you launch any EC2 Linux instance, you should select a key pair for that particular instance. AWS key pair will be in the standard private key format with.pem file extension. But if you are using PuTTY on your Windows laptop to login to AWS instance, you have a problem. PuTTY doesn’t support PEM format.
  • To create a key pair, use the create-key-pair command with the -query option, and the -output text option to pipe your private key directly into a file. $ aws ec2 create-key-pair -key-name MyKeyPair -query 'KeyMaterial' -output text MyKeyPair.pem.

Replace PublicKeypair with the public key retrieved in step 2. Be sure to enter the entire public key, starting with ssh-rsa.

7. Choose Save.

8. Start your instance.

9. After the cloud-init phase is complete, validate that the public key was replaced.

Important: Because the script contains a key pair, remove the script from the User Data field.

10. Stop your instance.

11. Choose Actions, Instance Settings, and then choose View/Change User Data.

13. Start your instance.

Note: If your instance is Amazon Linux 2 2.0.20190618 or later, you can use EC2 Instance Connect to connect to the instance.

Method 2: Use AWS Systems Manager

Aws Ec2 Lost Key Pair

If your unreachable instance is listed in AWS Systems Manager as a managed instance, you can use the AWSSupport-ResetAccess document to recover from a lost key pair scenario. This Automation document uses the EC2Rescue for Linux tool on the specified EC2 instance to automatically generate and add a new SSH (Public/Private) key pair.

Create New Key Pair Ec2 Instance

The new SSH private key for your instance is encrypted and saved in the Parameter Store. The parameter name is /ec2rl/openssh/instance_id/key. Create a new .pem file with this parameter's value as its content and use it to connect back to your unreachable instance.

Note: The Automation workflow creates a backup, password-enabled Amazon Machine Image (AMI). The new AMI is not automatically deleted and remains in your account.

To locate these AMIs:
