Re: Unlock LUKS with login/password

I have an idea about how modern linux should work with encrypted LUKS partitions.


I'm using LUKS for a long time on both my personal (desktop) and professional (laptop) computers. Since they are single user (me), I use autologin in the display manager, lightdm in my case. Because there is only one slot configured in LUKS, I'm sure this is me, so lightdm can autologin safely.

However, you are proposing to solve the case for multiple user computers. In that case, I would think about a much simpler design:

- Remember which slot was used to unlock the LUKS root partition

- Make a map with slot -> user to autologin

- Autologin that user on boot

No more passing password, no more password update headache. But only a root user can update the map "slot -> user".
