This is mostly a reminder for myself. But maybe you are also interested in this :)

So this is the way you can access a server via ssh without getting asked about passwords:

​1. Create a SSH key. You might want to take a look at this to get one.

​2. Copy the result of the following command:cat .ssh/

​3. Connect to the server: ssh user@server.tld + Enter password

​4. Create the .ssh folder if not yet done:mkdir ~/.ssh

​5. pico ~/.ssh/authorized_keys => Paste the clipboard.

​6. exit

​7. ssh user@server.tld => You should now be connected without entering a password!
