You can now authenticate to your server with the key pair, but at the moment you would need to enter the passphrase every time you connect.

If not, just replace the key path ~/.ssh/id_rsa.pub above with your own key name.Įnter your user account password for that SSH server when prompted. This also assumes you saved the key pair using the default file name and location. Replace the user and server with your username and the server address you wish to use the key authentication on. Copy the public half of the key pair to your cloud server using the following command Note that some automation tools might not be able to unlock passphrase-protected private keys. Enter the password you wish or continue without a password. This is a simple password that will protect your private key should someone be able to get their hands on it. (Optional) Create a passphrase for the key when prompted Enter a new name or use the default by pressing enter.

The key generator will ask for location and file name to which the key is saved to. Generate a new key pair in a terminal with the next command ssh-keygen -t rsa PuTTY users should skip to the next section. Now continue on your own computer if you are using Linux or any other OS that has OpenSSH. However, note that since the keys are stored in your user home directory, every user that wishes to connect using SSH keys for authentication has to repeat these steps on their own profile. This creates a secure location for you to save your SSH keys for authentication. Then restrict the permissions to that directory to just yourself with the command below. To add an SSH key pair, first, create a hidden folder to your user account home directory on your cloud server with the following command. Try UpCloud for free!

When keys are implemented correctly they provide a secure, fast, and easy way of accessing your cloud server.įollow our guide and learn how to set up your first SSH keys for authentication using OpenSSH or PuTTYTray. They can greatly simplify and increase the security of your login process. Therefore, be extremely careful as you experiment with this process.Use SSH keys for authentication when you are connecting to your server, or even between your servers.

Though this can be a simple and efficient method to install keys, misconfigured keys may result in security issues or getting locked out of the system. This guide showed you how to use the ssh-copy-id command to install SSH keys on remote hosts. -n flag: This flag performs a dry-run that prints the keys intended for installation without installing them on the remote host.This flag is used when the default SSH port is not being used. -p flag: This flag specifies the SSH port to connect to the remote host.The -f flag adds a key, often resulting in multiple copies of the same key installed on the server. -f flag: This flag enables forced mode, which does not check whether the key is pre-configured in authorized_keys on the server.If you fail to specify the -i argument, all the files in the ~/.ssh directory with the matching pattern *.pub will be added. -i argument: This argument specifies the identity file to be used, i.e., copied to the specified remote host.To view the help page, use the command ssh-copy-id -h or use the ssh-copy-id command with no arguments. You can modify how the ssh-copy-id command works by using the provided arguments. The system may prompt you to enter the passphrase of the key that you set up earlier. The command above should allow you to log in to the remote host without asking for the user’s password. This tool generates public and private key files stored in the ~/.ssh directory, as shown below.Įnter passphrase for key '/root/.ssh/id_rsa': To generate an SSH key, use the ssh-keygen tool that comes as a part of OpenSSH. To use an SSH key, we will begin by generating a key. SSH keys are automated, and once authorized, do not require a password at each login. SSH keys are more secure than raw passwords and provide a much more efficient way of logging into SSH. Public SSH key authentication is an SSH authentication method that allows users to use cryptographically generated keys to log into remote servers.

NOTE: If you already know how SSH public key authentication works, feel free to skip this part and dive deeper into how to use the ssh-copy-id command immediately. Before we dive into how to use the tool, we will first discuss how SSH public key authentication works. Using ssh-copy-id is simple because the script makes the public key authentication process easier and more efficient. ] hostname -f: force mode - copy keys without trying to check if they are already installed -n: dry run - no keys are actually copied -h |-?: print this help
