Connect to VPS Using SSH Key
Secure Shell (SSH) keys provide a more secure way of logging into a virtual private server (VPS) compared to passwords. By using SSH keys, you can establish a secure connection between your local computer and the VPS without the need to enter a password every time you connect.
In this article, we will guide you on how to connect to your VPS using an SSH key.
Step 1: Generate SSH Key Pair
The first step in connecting to your VPS using an SSH key is to generate a key pair on your local computer.
To generate an SSH key pair, open your terminal and run the following command:
ssh-keygen -t rsa -b 4096
Follow the on-screen prompts to generate your SSH key pair. By default, the keys will be stored in /home/your_username/.ssh/ directory.
Step 2: Copy Public Key to VPS
Once you have generated your SSH key pair, you need to copy the public key to your VPS.
You can use the following command to copy your SSH public key to your VPS:
ssh-copy-id user@vps_ip_address
Replace user with your VPS username and vps_ip_address with your VPS’ IP address.
Step 3: Connect to VPS Using SSH Key
With the SSH keys set up, you can now connect to your VPS using the following command:
ssh user@vps_ip_address
Enter your SSH key passphrase when prompted, and you will be logged into your VPS securely without the need for a password.
Conclusion
Using SSH keys to connect to your VPS is a more secure and convenient method compared to traditional password authentication. By following the steps outlined in this article, you can establish a secure connection to your VPS effortlessly.
Make sure to keep your private SSH key secure and never share it with anyone to maintain the security of your VPS.
