I don't know your setup, but a few Ideas: - program just runs 1 month, put a raspberry in epoxy - generate a long password (long enough so it doesn't matter you saw it a few times), find some reminder service or ask a friend to mail it back in a month, delete all local evidence of the password - generally sealing all relevant equipment with a lock could work. Key has to go to someone else.
