[FIXED] How to regain control over an Ubuntu Remote Desktop running on a Google Cloud VM after being locked out?

Issue

Following these instructions I set up a remote desktop computer running on a Google Cloud Virtual Machine. I had a perfectly functional Ubuntu 20.04 LTS machine controllable from my browser. I left it alone for a few minutes, and now the screen is locked:

I have not specified any password before. A simple enter does not let me in.

How can I regain control over this machine?

Solution

You can connect to your VM using SSH and then you log in as root using sudo su. Then you can change the password of any user using passwd USER_NAME
