Strongsec

STRONGSEC is a secure, modern password manager and generator built for real-world usage.

🔐 Security First Approach
• All passwords are encrypted locally using AES-GCM
• Master password is never stored and is used to derive keys via PBKDF2
• Vault remains protected with manual lock and secure session handling
• By default, vault keys are kept in memory during the active session
• Optional “Remember this device” mode keeps the vault unlocked on trusted personal devices until the user manually locks it
• Plaintext passwords and the master password are never stored

🧠 Smart Autofill & Detection
• Automatically detects login and signup forms
• Context-aware system distinguishes between login and registration flows
• Intelligent multi-account support for websites with multiple saved credentials
• Works reliably even on modern SPA websites (React, Vue, etc.)
• Improved signup save suggestions for modern registration flows

⚡ Password Management
• Generate strong and unique passwords instantly
• Automatically save newly created credentials after signup
• Secure autofill for login forms
• Inline UI suggestions directly on password fields
• Optional trusted-device unlock experience for smoother daily use

🚨 Breach Detection (Have I Been Pwned)
• Checks passwords using the Have I Been Pwned API
• Uses k-anonymity model, so your full password is never sent
• Alerts users if a password has been exposed in known data breaches

🛡️ Privacy First Design
• All password encryption and vault operations happen locally on your device
• Your plaintext passwords never leave your browser
• No servers, no cloud password storage, no account sync
• No tracking, no analytics, no data collection
• Passwords are never stored in plain text

🔐 New in this update
• Added optional “Remember this device” mode for trusted personal devices
• Improved signup save suggestion reliability on modern websites
• Fixed popup button layout and readability issues

STRONGSEC is designed for users who want a lightweight, privacy-focused and secure alternative to traditional password managers.
