Create and manage key pair

A key pair is a credential used to verify authentication when connecting to an instance, and it consists of a public key and a private key.
The public key is stored on the instance, and the private key is stored and managed directly by the user. Because anyone who has the private key can connect to the instance, the user who created the private key must keep it secure.

- You can view it in Virtual Machine > Key pair > [⋮] button > View public key

⚠️ Because anyone who owns the private key can connect to the instance, pay special attention to security management.
