About randomness & privacy

  • All IDs and passwords are generated locally using the browser's built-in crypto-strength random source (crypto.getRandomValues) — no network calls, no storage, no duplicate output.
  • UUID v4 has 122 random bits; the collision probability is about 1 in 2¹²², so it's safe as a database primary key or request-tracing ID.
  • For passwords, use 16+ characters with mixed case and digits; add symbols based on target-system limits.
