An SSH key is a secure method of authentication used in the SSH (Secure Shell) protocol to connect to and authenticate with remote servers. It serves as an alternative to password-based logins and consists of a pair of cryptographic keys: a public key, which is shared with SSH servers, and a private key, which remains confidential to the user.
SSH keys can be managed with SSH key agent manager in Remote Desktop Manager, allowing you to store all your SSH keys in memory, already decoded and ready to use, thus facilitating seamless authentication.
