Passphrases in crypttab(5) are for disks, disk partitions, virtual 
devices, etc., and are unrelated to user passwords.  Changing one does 
not affect the other, and vice versa.

If you are using LUKS to encrypt a partition, LUKS supports more than 
one passphrase.  See cryptsetup(8).  To change the passphrase, I would 
add the new passphrase, reboot, and enter the new passphrase to verify. 
When you are confident the new passphrase works, delete the old passphrase.
