Version is ESXi 6. (Sorry I didn't mention that)
I am unable to log back into my web gui, ssh, and client. They all keep saying it's the incorrect password when I know it is the right password. I verified this by logging into the physical machine itself.
I only have one account which is root. I didn't install vCenter or do any domain stuff (besides messing around in pfSense).
This has happened several times and I'm not sure what's going on. I had to wipe my machine and reinstall everything again.
I only have a pfsense and Ubuntu machine on there.
