Keepass Cat tekijä 神楽

Keepass Cat is a lightweight, open-source KeePass browser extension that connects your existing KeePass database (.kdbx) on your WebDAV cloud directly to your browser, enabling password autofill and full entry management — create, read, edit, and delete. You can ditch local KeePass / KeePassXC clients entirely: a browser extension is all you need. Your data lives on your own WebDAV server (Nextcloud, ownCloud, and other WebDAV-compatible services) — it stays yours and is never uploaded to any third party.
Core features
- One-click autofill: intelligently detects username/password fields and fills them accurately
- 4-level URL matching: exact → same-origin → same-domain → regex, ranking the best-matching entry first with a live match count on the icon
- Full entry management: create, edit, and delete entries and groups right in the popup, with changes written back to your database
- TOTP two-factor authentication: view and copy one-time codes (with a countdown), including editing support
- Strong password generator: generate high-entropy random passwords in one click
- Clipboard protection: auto-clears copied secrets after a configurable timeout
Security & privacy
- Your master password is decrypted only in memory (AES-CBC + Argon2 KDF); plaintext is never persisted
- Websites and other extensions cannot read your password data
- Fully open source and auditable
Getting started
1. Configure your WebDAV server in Settings
2. Scan for and select your .kdbx database file
