How to Setup SSH Passwordless Login in Linux
Logging into your Linux server without entering a password every time can save you time and make the login process more efficient. In this article, we will guide you through the process of setting up SSH passwordless login on your Linux system.
Step 1: Generate SSH keys
The first step in setting up passwordless login is generating SSH keys on your client machine. To do this, open a terminal and run the following command:
ssh-keygen
Press Enter to accept the default location for saving the SSH keys. You can also set a passphrase for added security, but for passwordless login, it’s recommended to leave it empty.
Step 2: Copy the public key to the server
Once you have generated the SSH keys, you need to copy the public key to your Linux server. Run the following command to do this:
ssh-copy-id username@server_ip
Replace username with your username on the server and server_ip with the IP address of your server. You will be prompted to enter your password for the last time, after which your public key will be added to the server’s authorized_keys file.
Step 3: Test passwordless login
Now that you have copied the public key to your server, you can test passwordless login by running the following command:
ssh username@server_ip
If everything was set up correctly, you should be logged into your Linux server without entering a password. Congratulations, you have successfully set up SSH passwordless login!
