Passa - Password Manager Firefox

Passa - Password Manager

By: Ovansa
A secure, zero-knowledge password manager that saves, generates, and autofills passwords with optional encrypted cross-browser sync.

Features & Capabilities

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.

A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
