Hi @sidharthsurana,
/proc/ is not mounted seems to be an indication. How did you configure your system? (vhw,efi/secureboot, physical scsi device/vmdk, serial port/network mounted disk image, filesystem/...)
Password reset on an ova setup works flawlessly. Tested e.g. on photon-hw15-5.0-dde71ec57.x86_64.ova vanila setup.

Btw. on the docs page the account unlock chapter is old, sbin/faillock --reset --user root works.

Thanks to @YustasSwamp for helping find the workaround:

In some cases if /proc and /sys are not mounted by default then additional commands are required once booted:

# mount none /proc -t proc
# mount none /sys -t sysfs
### next command is required if you didn't specify rw cmdline parameter
# mount -o rw,remount /  
# passwd
Once password changed
# umount /
# reboot -f
