Using Pre-Generated SSH Keys and Disabling Password Authentication for Secure Access to ServerStadium’s Cloud Instances
Secure Shell (SSH) keys offer a more secure method of logging into a server than using a password alone. ServerStadium’s cloud instances are configured with pre-generated SSH keys for this purpose. This tutorial will guide you on using these SSH keys for secure access and disabling password authentication for your ServerStadium cloud instance.

Step 1: Register Your Account
If you haven’t already, you’ll need to create an account on our Registration Page. Once registered, you’ll have access to your personal Cloud Dashboard.
Step 2: Add Your Cloud Instance
From your Cloud Dashboard, click the ‘Add VM’ button. Choose a cloud instance that suits your needs and budget. For more detailed information about our offerings, you can visit our Pricing Page.
Step 3: Retrieve Your SSH Key
Once your cloud instance is created, you can retrieve the pre-generated SSH key from your Cloud Dashboard. Save this key to a secure location on your local machine, typically in the ~/.ssh/ directory.
Remember to set the correct permissions for your SSH key file with the following command:
chmod 600 ~/.ssh/your_ssh_key
Replace “your_ssh_key” with the filename of your SSH key.
Step 4: Disable Password Authentication
To enhance security, you can disable password authentication and allow only SSH key authentication. Log into your ServerStadium cloud instance and edit the SSH configuration file:
sudo nano /etc/ssh/sshd_config
Find the line that says PasswordAuthentication and change it to no. If the line is commented out, remove the # at the start of the line. Save and exit the file.
After making this change, you must restart the SSH service for the changes to take effect:
sudo systemctl restart ssh
Step 5: Login Using SSH Keys
Finally, log into your ServerStadium cloud instance using the SSH key with the following command:
ssh -i ~/.ssh/your_ssh_key your_username@your_server_IP_address
Replace “your_ssh_key” with your SSH key filename, “your_username” with your actual username, and “your_server_IP_address” with the IP address of your ServerStadium cloud instance.
Conclusion
Congratulations! You’ve successfully used pre-generated SSH keys for secure access and disabled password authentication on your ServerStadium cloud instance. Now, you can log into your instance securely without needing a password.
