You can use cryptsetup to add and remove luks passphrases. Note that if there 
are backups of the luks header for that partition, they could potentially 
be used with the old passphrase to decrypt the file system on partition.

There should be a way to unsave the passphrase, but I don't know how to 
do it. Arguably saving the passphrase by default is a bug.
