    Version 2.0 – New Security Protocol (QR Login v2)
    • Unique browser-phone pairing: The phone now only accepts QR codes signed by your specific browser.
    • No secrets in the QR code: The QR code no longer contains sensitive data; the response is end-to-end encrypted (ECDH + AES-GCM).
    • Domain-specific autofill: Data is only filled on the exact website for which the code was generated.
    • Reduced permissions: The extension now only requires activeTab and scripting permissions.
    Important: After the update, you must re-pair your browser in the SeifPro app (Settings → Paired Browsers). This requires the latest version of the Android app.
