Hey @chamas and welcome to the forums!
Yes, when you hold down the ESC key, it drops you into the Grub console. You only need to tap the button once.
The moment you get the Grub Menu, you can then go to the Advanced Options and hit Enter. Select one of the Recovery options and it will bring you to a window with a variety of options that you can navigate with your arrow keys and select with the Enter key.
Select the Drop to root terminal and hit Enter. Once in terminal, execute:
passwd $(ls /home)
This will read the folder within the Home directory and pull your username. Then, it will ask you to input a new password, twice. Once done, execute:
reboot
And you’ll be good to go!
