NullID public guide
Generate passwords and passphrases locally
Password & Passphrase creates local password and passphrase candidates and can generate password storage verifier records for applications or local prototypes.
Generation controls
Password generation supports length, character sets, ambiguity avoidance, sequence and repeat blocking, and minimum unique-character settings. Passphrase generation supports dictionary profiles, word counts, separators, casing, numbers, symbols, and unique-word enforcement.
Hashing and verification
Password storage records can use Argon2id when supported by the runtime or PBKDF2-SHA256 for compatibility. Legacy fast hash options are migration-only because they are not slow password KDFs.
How to use it
- Choose a password or passphrase mode.
- Adjust generation settings or apply a preset.
- Review the strength lab and batch candidates.
- Copy with clipboard hygiene when needed.
- For storage records, save the full encoded record with salt and cost settings.
Limitations
- Generated passwords should still be stored in a dedicated password manager.
- Strength estimates are model-based guidance, not a guarantee.
- One-way password records cannot recover the original password.
- Clipboard auto-clear is best-effort.
