[Caveat: this is sort of from memory; I don't have a luks-encrypted
device handy for testing...]
First, add a second key (password):
cryptsetup luksAddKey /dev/XXX
Then delete the original key
cryptsetup luksKillSlot /dev/XXX 0
You need to be careful to get the slot numbers correct. Use the
luksDump option to see how things are setup on your system.
