We’ve all been there. You turn on a machine in your home-lab, your Raspberry Pi, or an old PC and you’ve forgotten your password. At this point you start Googling, and that might be what brought you here.
The other options that you find to do this may be a little clunky, but if you have your SSH key installed on the remote machine, and Docker, you can reset your password in a few simple commands. It’s not particularly novel, or ground-breaking, but this may be useful to you at some point as it was to me today.
