Features & Capabilities

SandPass is a free, zero-knowledge password manager that keeps your passwords truly private. Unlike most password managers, your master password never leaves your device.

🔒 Zero-Knowledge Password Vault Your master password never reaches our servers. We use OPAQUE (RFC 9807) authentication - the server never sees your password, not even during login. Your password vault is encrypted on your device before it ever syncs.

🛡️ Military-Grade Password Encryption

  • AES-256-GCM for your password vault
  • Argon2id key derivation (OWASP recommended)
  • Per-device key wrapping

✨ Password Manager Features

  • Secure password generator (strong, unique passwords)
  • Autofill passwords on any website
  • Cross-device password sync (end-to-end encrypted)
  • TOTP two-factor authentication codes
  • WebAuthn / passkey support
  • Dark mode
  • Breach monitoring (alerts if your passwords are leaked)
  • Import passwords from other password managers

🔐 Security First

  • Open-architecture encryption with audited libraries
  • Anti-phishing: passwords are domain-locked
  • Session tokens (not JWT) for instant revocation
  • Progressive lockout on failed password attempts

🆓 Free Password Manager SandPass is a free password manager - no subscription, no hidden fees. Save unlimited passwords across unlimited devices.

Why SandPass? Most password managers can technically read your passwords if their servers are compromised. SandPass cannot - your passwords are encrypted before they leave your browser. Even our team cannot read them.

Switch to SandPass - the secure, free, zero-knowledge password manager for Firefox.

Is Password Manager Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. 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.

Password Manager requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
  • High ****** ******* *** ********* ********* ******** ***** *** ** ********** ****** * ******** ******* *****
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.

Password Manager may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.

Risk likelihood analysis details
  • High This extension was recently updated in the past month. New updates may not be stable or safe.
  • High **** ********* *** *** **** ****** ********* ********** *** *** ** ****** ** *****
  • Medium **** ********* *** ***** ** *** **** * ******* *** ********** *** *** ** ****** ** *****
