How to Add SSH Keys to New or Existing GPU Instances

Solidus AITECH Compute Marketplace GPU instances are Linux-based virtual machines (VMs that run on top of virtualized hardware. Each GPU instance you create is a new server you can use, either standalone or as part of a larger, cloud-based infrastructure.

You can manage your GPU instances using password-based logins, but we strongly recommend using SSH key pairs instead. SSH keys are more secure than passwords and allow you to log in without having to remember long passwords.

To use SSH keys with your GPU instances, you need to:

1. Create an SSH key using an SSH client installed on your local computer.
   • OpenSSH is included on Linux, macOS, and Windows Subsystem for Linux (WSL).
   • Windows users without Bash can use PuTTY.
