SSH (Secure Shell) keys are a way of securely identifying yourself to a remote server. SSH keys are a more secure and convenient way to authenticate yourself to a remote server than using a password.nnAn SSH key pair consists of a private key and a public key. The private key is kept secret and never shared, while the public key can be shared freely. When you attempt to connect to a server with SSH, the server checks if your public key matches the private key you're using to authenticate. If the keys match, the server allows you to access your account without requiring a password.nnUsing SSH keys has several advantages over using passwords for authentication. For one, SSH keys are much more secure than passwords because they are longer, more complex, and never transmitted over the network. This makes it much harder for an attacker to intercept and use your credentials to gain unauthorized access to your server. Additionally, SSH keys are more convenient because you don't have to remember or type in a password each time you connect to your server.nnIn summary, using SSH keys for authentication is a more secure and convenient way to connect to a remote server than using passwords.
