## Description

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.
