    Learn how to setup passwordless SSH key-based authentication for multiple remote Linux servers simultaneously using a shell script in this TecMint tutorial. 

     

    SSH Key-based authentication (also known as public-key authentication) allows for password-less authentication and it is a more secure and a much better solution than password authentication. One major advantage of SSH password-less login, let alone security is that it allows for automation of various kinds of cross-server processes.

    In this article, we will demonstrate how to create an SSH key pair and copy the public key to multiple remote Linux hosts at once, with a shell script.
