Step 4 – Reset the password for the root account.

When it’s done, simply reboot your system and try to login using the newly resetted password. You should be able to login into your Proxmox VE system.
Final Notes
You might want to document this procedure in case you loose your password for the root account. The Proxmox VE 2.0 has a role based model administration that should help you minimize annoyance of loosing password. I’m assuming that with the role based models, organization will define more than one full administrative account in order to have a secondary account that could be used to recover or access the system in case of problem with the root account. We will see what future brings.
That’s it for this post
Till next Time …See you
