til/ssh/using_a_public_key_to_login.md

You can generate authentication keys and use it with ssh to login. First run the below command if you don't have any (it won't overwrite if you already have one):

ssh-keygen

Then copy your public key to remote server with this:

ssh-copy-id name@host

From now on, you should be able to login with ssh name@host without having to enter your password.
