Registering an IAM User's Public SSH Key
There are two ways to register a user's public SSH key:
An administrative user can assign a public SSH key to one or more users and provide them with the corresponding private key.
An administrative user can enable self-management for one or more users.
Those users can then specify their own public SSH key.
For more information how administrative users can enable self management or assign public keys to users, see Editing User Settings.
Connecting to Linux-based instances by using SSH in a PuTTY terminal requires additional steps. For more information, see Connecting to Your Linux Instance from Windows Using PuTTY and Troubleshooting Connecting to Your Instance in the AWS documentation.
The following describes how an IAM user with self-management enabled can specify their public key.
To specify your SSH public key
Create an SSH key pair.
The simplest approach is to generate the key pair locally. For more information see How to Generate Your Own Key and Import It to Amazon EC2.
If you use PuTTYgen to generate your key pair, copy the public key from the Public key for pasting into OpenSSH authorized_keys file box. Clicking Save Public Key saves the public key in a format that is not supported by MindTerm.
Sign into the AWS OpsWorks console as an IAM user with self-management enabled.
If you sign in as an account owner, or as an IAM user that does not have self-management enabled, AWS OpsWorks does not display My Settings. If you are an administrative user or the account owner, you can instead specify SSH keys by going to the Users page and editing the user settings.
Select My Settings, which displays the settings for the signed-in IAM user.
On the My Settings page, click Edit.
In the Public SSH Key box, enter your SSH public key, and then click Save.
To use the built-in MindTerm SSH client to connect to Amazon EC2 instances, a user must be signed in as an IAM user and have a public SSH key registered with AWS OpsWorks. For more information, see Using the Built-in MindTerm SSH Client.
