After you review your configuration and click "Launch" a popup will come up asking you for a key pair. It's important for you to understand what it's asking for. It is the same type of SSH key pair that you've created and used in the [[OPS245 OSL740 Lab 7]]. Remember that your private key is yours, it's private to you, and not for anyone else to see. AWS is asking you to give them the public key which is the pair of the private key which you wish to use to log in to your new VM. In this case your private key is the effective equivalent of the root password.
