How to SSH Without Password in Linux: A Step-by-Step Guide

SSH, or Secure Shell, is a common method used to access and manage remote servers. One of the conveniences of SSH is the ability to login without entering a password every time. Here's a step-by-step guide on how to SSH without a password in Linux:

1. Generate an SSH key pair using the following command: ssh-keygen -t rsa.
2. Press enter to save the key in the default directory, usually ~/.ssh/id_rsa.
3. Copy the public key to the remote server using the command: ssh-copy-id user@remote_server.
4. Enter your password when prompted.
5. SSH into the remote server without entering a password using: ssh user@remote_server.

By following these steps, you can securely SSH into a remote server without the hassle of entering a password each time. Remember to keep your private key secure and never share it with anyone.
