- Additionally, you should set a GRUB password. This is not your LUKS password, but it's a password that you have to enter to see - GRUB. This protects your system from an attacker simply booting a live USB and re-flashing your firmware. This should be different than your LUKS passphrase and user password. -

- Use of the diceware method is recommended, for generating secure passphrases (as opposed to passwords). -

- The GRUB utility can be used like so:
- $ grub-mkpasswd-pbkdf2 -

- Give it a password (remember, it has to be secure) and it'll output something like:

- MAKE SURE TO DO THIS ON grubtest.cfg *BEFORE* DOING IT ON grub.cfg. - Then select the menu entry that says Switch to grubtest.cfg and test that it works. - Then copy that to grub.cfg once you're satisfied. - WHY? BECAUSE AN INCORRECTLY SET PASSWORD CONFIG MEANS YOU CAN'T AUTHENTICATE, WHICH MEANS 'BRICK'. -

-

- (emphasis added, because it's needed. This is a common roadblock for users) -

- -

- Obviously, replace it with the correct hash that you actually got for the password that you entered. Meaning, not the hash that you see above! -

+ Refer to this guide for further guidance + on hardening your GRUB configuration, for security purposes. +

- After this, you will have a modified ROM with the menu entry for cryptomount, and the entry before that for the GRUB password. Flash the modified ROM + Flash the modified ROM using this tutorial.
