Passhash Redux av eddyecho

Passhash Redux generates unique, strong passwords for every site from a single master key. Your master key is never stored or transmitted — no accounts, no databases, no breach risk. Your master key never leaves the extension — only the derived password is sent to the page.

How it works: enter your master key and the extension produces a deterministic password unique to each site. Same inputs always produce the same password, so there's nothing to remember but your master key.

Features:
- Double-click any password field, right-click and select "Hash password," or use the keyboard shortcut to open the hasher
- Visual markers highlight detected password fields
- Per-site settings saved automatically (algorithm, size, character requirements)
- Multiple algorithms: SHA-1, SHA-256, SHA-384, SHA-512, Argon2id
- Configurable password length (4–26 characters)
- Import/export settings for backup and migration
- Standalone offline HTML version included
- Also available for Chrome/Chromium

Drop-in replacement for the original Password Hasher by Steve Cooper — your existing passwords will work.
