Passwordless SSH Login Ubuntu Setup

To set up SSH passwordless login on an Ubuntu system, you need to follow these steps:

1. Generate SSH key pair locally:
   Open the terminal and enter the following command to generate the SSH key pair:

ssh-keygen -t rsa

Set the key storage path and password according to the prompts.

1. Copy the public key to the remote server:
   Use the following command to copy the public key to the ~/.ssh/authorized_keys file on the remote server (create the file if it doesn’t exist):

ssh-copy-id user@remote_server_ip

Enter the password for the remote server user as instructed.

1. Test SSH keyless login:
   When connecting to the remote server again using SSH, you should be able to log in without entering a password.

ssh user@remote_server_ip

You have now successfully set up SSH passwordless login.
