Okay, so your private key pair has a passphrase? When you log into your server, does it confirm that you logged in using key? If you have trouble telling the difference, do you use your server user passhprase to log in or your private key pair passphrase to log in?

It is important to verify you are logging in using the key pair so you do not lock yourself out of the server.

```
