How to provide "private key" on first time log-on password challenge
Reference:Tutorial Initial server setup with ubuntu 14.04
Please explain this passage from the tutorial:
- Complete the login process by accepting the warning about host authenticity, if it appears, then providing your root authentication (password or private key). If it is your first time logging into the server, with a password, you will also be prompted to change the root password.
Specifically how do I, AT THIS POINT "provide your root authentication(private key)"
Please notice that during droplet creation I checked "use my ssh key" so no password has been sent to me. So I have no password. I would have to reset my password to get one mailed to me, but that defeats the purpose of attaching my ssh key in the first place. but more importantly
Here the instructions implies that at the point you can provide your password you have also the choice of providing your ssh key:
~ $ssh email@example.com The authenticity of host '22.214.171.124 (126.96.36.199)' can't be established. ECDSA key fingerprint is SHA256:TG8vLElrAYDRd6Mudtd+WklzpA1LTLnZQCKtRBxkn/4. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '188.8.131.52' (ECDSA) to the list of known hosts. firstname.lastname@example.org's password:
How do I instead of a password provide a private key?
Again: then providing your root authentication (password or private key)
