Passhash Redux by eddyecho

Passhash Redux generates unique, strong passwords for every site using a deterministic hash of your master key and the site tag. Your master key never leaves your device — no cloud sync, no storage, no risk of database breaches.

- Configurable password length (4-26 characters)
- Per-site settings (algorithm, size, character requirements)
- Password field detection with visual markers
- Import/export settings
- Standalone offline HTML version included
- Compatible with the original Password Hasher by Steve Cooper
