How to bypass root passsw/passphrase in Ubuntu 18 GRUB for beginners?

Question

There's user apps/desktop locked by a passphrase on an Ubuntu 18.04 after multiple unsuccessful attempts to enter user password. I can get into GRUB menu only, for root console it requires passwords. In detail the situation is described here [1]. I was curious how geniuses and PhDs of CS, as everybody here functionally is, can handle this situation.[1]https://ubuntu-mate.community/t/is-there-a-way-to-change-root-user-password-in-grub/25204/5

Remove the disk, mount it on another computer, edit /etc/passwd and /etc/shadow on that mounted disk, as described here: https://unix.stackexchange.com/questions/105278/resetting-pa...
