When using passwords for authentication, it is important to choose strong passwords that are difficult to guess. However, password-based authentication can be vulnerable to brute-force attacks, where attackers try to guess the password by trying many different combinations. Public-key cryptography provides a more secure alternative to password-based authentication. With public-key cryptography, each user has a public key and a private key. The public key is shared with the server, while the private key is kept secret. When a user attempts to authenticate, the server sends a challenge to the user. The user encrypts the challenge using their private key and sends it back to the server. The server then decrypts the challenge using the user's public key. If the decrypted challenge matches the original challenge, the user is authenticated.

Kerberos is a network authentication protocol that can be used with SSH to provide secure, single sign-on authentication. Kerberos uses a trusted third-party authentication server to issue tickets that can be used to authenticate to other services. This eliminates the need to enter a password for each service, making it more convenient and secure.
