If you are locked out of your Fedora instance and have lost access to the root account, you need to boot into single-user mode and reset the root password. These steps apply to Fedora versions 29 through 32.
Access the instance console in the Vultr customer portal.
Click the Send CtrlAltDel button on the top right of the web console.
You can also click the Server Restart icon.
