Passa - Password Manager by Ovansa

Passa is a zero-knowledge password manager that keeps you in control of your credentials.

Your vault is encrypted on your device with AES-256-GCM before it ever leaves the browser. Passa's servers never see your passwords, usernames, or notes - only you can decrypt your data.

Features:
- Save and autofill logins automatically as you browse
- Generate strong, unique passwords
- Built-in TOTP (two-factor) code generation
- Breach monitoring using Have I Been Pwned k-anonymity (your passwords are never sent)
- Optional encrypted sync to your own Google Drive or Dropbox
- Automatic clipboard clearing after copying
- CSV import and duplicate detection
- Right-click to generate passwords on any field

Zero-knowledge by design: encryption keys are derived from your master password using PBKDF2 (600,000 iterations) and never leave your device. The server stores only a bcrypt hash of a client-derived value - never your master password or vault contents.
