I’m playing with omarchy on an old laptop and decided I want to share it with my kids without sharing what I also set up as my sudo password.

```
Lsblk -f
```

Look for the one labeled crypto_LUKS

```
Sudo cryptsetup luksChangeKey /dev/nvme0n1p2
```

Then you will be asked for your sudo password, previous full disk encryption password, then the new one twice.

Now my laptop can be shared without sharing my private sudo password.
