Create a key pair Create a public/private key pair for a user connecting to a Linux server using OpenSSH. Use ssh-keygen to create the key pair. The creation of a public/private key pair must be done as a user with remote login privileges. If you do not specify the destination and file name, id_ed25519 and id_ed25519.pub will be created in /home/(user name)/.ssh/. On the way, enter the password for the key.
