Here’s a quick rundown of the steps:

Use the ssh-copy-id user@hostname command, replacing user with your username and hostname with your server’s IP address or domain name.
If manual copying is required, use cat ~/.ssh/id_rsa.pub | ssh user@hostname 'cat >> ~/.ssh/authorized_keys'.
Secure the SSH connection by editing the /etc/ssh/sshd_config file to disable password authentication.

Securing SSH Connection

With SSH keys generated and copied to your server, the next step is to enhance the security of your SSH connection. Disabling root login over SSH is a critical measure to prevent unauthorized access. To do this, edit the SSH configuration file /etc/ssh/sshd_config and set PermitRootLogin to no. After making changes, restart the SSH service to apply them.

Another good practice is to change the default SSH port from 22 to a custom port. This can reduce the risk of automated attacks. Here’s how to do it:

Open the SSH configuration file: sudo nano /etc/ssh/sshd_config
Locate the line with #Port 22
Remove the # and change 22 to your desired port number
Save the file and restart the SSH service: sudo systemctl restart sshd

Remember, after changing the SSH port, you will need to use the new port number when connecting to your server.
