NOTES ON PASSPHRASES
Mathematics can't be bribed. Make sure you keep your passphrases
safe. There are a few nice tricks for constructing a fallback,
when suddenly out of the blue, your brain refuses to cooperate.
These fallbacks need LUKS, as it's only possible with LUKS to
have multiple passphrases. Still, if your attacker model does not
prevent it, storing your passphrase in a sealed envelope
somewhere may be a good idea as well.
