So, you’ve gone cloud native and installed Photon OS. Since my team develops quite a few things here at VMware using Photon OS and docker, i’ve come across a situation where i’ve needed to reset Photon’s root password. Here is how it’s done.
Shutdown your PhotonOS VM and re-start it, press the ‘e’ button when you get to the boot screen (as seen below). This in turn will get you to Photon’s GRUB2 interface.
From there, the process is fairly simple, as all you have to do is to add a couple of parameters to the end of the linux boot parameters line.
This should look something like this when you’re done.
Now press Ctrl+X in order to continue with the boot sequence, and your boot process will end in a bash shell, punching in the ‘passwd’ command will reset your root user password.
And remember kids –
He who has console rights to server = owns root/admin privileges (true to any OS)
