SSH keys provide a more secure way of logging into a virtual private server with SSH than using a password alone. SSH keys are nearly impossible to decipher.

1. Create the key pair on the client machine

   ssh-keygen -t rsa

   Once you have entered the command, you will get a few more questions. Answer them all.

2. Copy the Public Key
   Once the key pair is generated, it’s time to place the public key on the remote server that we want to use.

   ssh-copy-id user@remote-server
