Secure Shell (SSH) is a cryptographic network protocol that is used for secure data communication, remote shell services, and command execution.
Public key authentication provides stronger security compared to passwords. It uses cryptographic keys, making it difficult for attackers to gain unauthorized access.
Skip the trouble of having to remember complicated passwords. Password management is not necessary with public key authentication; therefore, the chance of password theft is decreased.
If you combine public key authentication with passphrases it will provide an additional layer of security, this ensures that only authorized users can access the system.
Easily manage user access by distributing public keys. Adding or removing access can be done swiftly without changing passwords for all users.
