Hello Michel! Thank you for your prompt response. I will follow your advice. I did try some OpenSSH options before (ssh-keygen -i and such) but kept getting errors.

Reason why I’m so insistent is because I got locked out from my VM for some odd reason, and all contingencies do not seem to work, so I guess I would try to gain access through cloud console, and also learn from this experience.

I will dig more into the OpenSSH side of things. Thanks again!
