== Name

cryptsetup-luksRemoveKey - remove the supplied passphrase from the LUKS device

== SYNOPSIS

*cryptsetup _luksRemoveKey_ [<options>] <device> [<key file with passphrase to be removed>]*

== DESCRIPTION

Removes the supplied passphrase from the LUKS device.
The passphrase to be removed can be specified interactively, as the positional argument or via --key-file.

*<options>* can be [--key-file, --keyfile-offset, --keyfile-size, --header, --disable-locks, --type, --timeout, --verify-passphrase].

*WARNING:* If you read the passphrase from stdin (without further argument or with '-' as an argument to --key-file), batch-mode (-q) will be implicitly switched on and no warning will be given when you remove the last remaining passphrase from a LUKS container.
Removing the last passphrase makes the LUKS container permanently inaccessible.
