How to Copy SSH Keys to Another Machine | VPS Tutorial

Using SSH keys is the most secure and convenient way to log in to another machine. Instead of typing your password every time, you can authenticate using a public/private key pair.

Copying your SSH public key to another machine allows secure, passwordless logins. The simplest method is ssh-copy-id, which handles everything automatically. If needed, you can do it manually by creating .ssh/authorized_keys and appending your public key. Proper permissions are crucial to ensure the key works and remains secure.
