The sshpass command takes uses the -p to take the password as an argument and then provides it to the ssh command for authentication. Can be used with a variety of other command line tools, such as GPG, SCP, and Rsync.Compatible with multiple operating systems, including Ubuntu, Debian, Fedora, and Arch Linux.Ability to use environment variables to pass the password.Supports password authentication for SSH connections.Ability to provide the password on the command line or in a file.The sshpass utility has several features that make it useful for automated SSH logins. The password prompt utilized by Secure Shell (SSH), on the other hand, is hardcoded into the sshpass utility. However, sshpass runs SSH and supplies password to ssh prompt in a dedicated TTY, fooling SSH into believing that an interactive user is entering the password. SSH requires direct TTY access to guarantee that the password is being inputted by an interactive keyboard user. The sshpass utility was created to execute SSH using keyboard-interactive password authentication in a non-interactive manner. This is because the password is passed in cleartext on the command line and saved in the user's shell history file, which other system users with access to the system can potentially view. The sshpass command is generally discouraged because it is not regarded as a secure authentication method. This can help save time and streamline processes, especially when managing multiple servers or devices. This tool is convenient when you need to automate SSH logins, such as in a script, without having to manually enter a password each time. The sshpass command is a non-interactive ssh password authentication command line tool that can assist system administrators in automating SSH logins. ![]()
