Choose long, memorable phrases from unrelated words, add spacing or punctuation you love, and store them in a trustworthy manager. Avoid reuse entirely. Periodically rehearse emergency unlocks. Encourage collaborators to adopt the same standard, so shared vaults and devices remain secure without turning every login into a dreaded puzzle.
Back up keys and recovery codes in multiple sealed envelopes, stored separately. Consider hardware tokens for critical machines, labeling spares clearly. Verify fingerprints before trusting devices. Keep a revocation plan ready, tested, and written plainly, because clarity under stress beats cleverness that only made sense last summer.
Even when content is locked down, filenames, timestamps, and link graphs whisper. Randomize export names, strip EXIF from images, and avoid sensitive titles on shared pages. Prefer private share links with expiration. When in doubt, move discussions to end-to-end channels and publish sanitized summaries later, reducing accidental disclosure.
