The process was successful if you see the welcome message of the Ubuntu Hetzner instance

Enter the passphrase you set for the SSH Key.

Ssh Type yes in order to add the fingerprint to the known_host Replace the with the IP address of the created Hetzner Instance

On your local computer start the login.

Copy the IP address of the Hetzner instance.

Step 4 - Test the login with the SSH Key from your local computer

Create the Instance by clicking CREATE & BUY NOW.

On the SSH Key field make sure you click the suggested SSH Key that you added on the previous step.

Select a Location, an Ubuntu:20.04 Image, a Standard Local (NVMe SSD) Storage Type, an Instance Type and other desired configurations.

On left side menu of the project where you added the SSH Key in previous step select the Servers menu.

Step 3 - Create a Hetzner instance with the added SSH Key on the Cloud Console This specific SSH Key is ready to be used every time you create a new instance for this specific project

Add a name for the SSH Key in order to identify it on the Hetzner Cloud Console or leave the automatically generated name based on the key comment.

Paste the SSH Key in the marked area on your hetzner account.

Copy the content of your id_rsa.pubfile from your local machine to the clipboard by selecting the output and using ++c.

On your local machine execute the command cat /home/user/.ssh/id_rsa.pub to see the content of your file or open it in the editor.

On left side menu of your project select the Security menu.

That means that you need to repeat this step with the same key or different keys for each new project. In this step it is important to clarify that the SSH keys are not shared between Hetzner projects. Step 2 - Add the SSH Key to your Hetzner Cloud Console

The file id_rsa.pub is the public key the server needs to authenticate the user and the file id_rsa is your private key that no one should have access to except for you, especially if you skip the step of setting up a passphrase By default this command will create a public and a private Key named id_rsa.pub and id_rsa respectively and they will be saved on the path ~/.ssh/. Yet it protects anyone from copying the file and using it on another computer.

You can configure your ssh client to communicate to keypass, to avoid entering the password every time, but understand, that typically keypass is active all the time, so direct access to your logged in session would not prevent unpermitted access to the server in that case. This passphrase will protect the private key, so no one can access the server even if he has access to your computer. We strongly recommend to set a passphrase in order to set up a secure instance. There are many tutorials on Youtube and the whole internet, where adding a passphrase is just omitted or not recommended. Then you should set your own passphrase for adding more security to the server. If you want to name the file to be able to distinguish between multiple keys for multiple different servers, you can enter /home/user/.ssh/server01 where you replace user with your username You could just hit enter in order to leave the default name ('id_rsa') and location ( /home/user/.ssh/). Then you will be asked for the filename/location of the RSA Key. For example SSH-Key - MacbookPro 13 Inch -t rsa -b 4096 -C "some comment here" Some information about the computer itself should be useful. It is recommended to add a comment at the end in order to identify the SSH Key in the future.

You need to create an SSH Key on your local machine.

ssh-keygen, cat and nano installed on your local computer.

Permissions for creating a Hetzner Project and a Hetzner instance.

In this tutorial we will use rsa which is good enough and has higher compatibility with a lot of applications. You also can use different algorithms like ECC (Elliptic Curve Cryptography) using the standard ed25519. If you increase the password strength, it gets very difficult to remember the password and the use of a password manager is unavoidable.

In this tutorial I will guide you how to setup the secure login with your SSH Key on a new Hetzner instance. In order to access your Hetzner instance from your local computer in a safe way, it is recommended to make use of an SSH Key.
