Seif Pro QR Login by Seif Pro - QR Login

Seif Pro QR Login is the browser companion of the SeifPro Android password manager. Open a login page, click the extension, scan the QR code with your phone, confirm – and the login form is filled in, without typing a password on your computer.

HOW IT WORKS
1. Pair once: the extension shows a pairing QR code. Scan it in the SeifPro app (Settings → Paired browsers) and check that the fingerprint matches.
2. Log in: on any login page, click the extension and scan the QR code with the SeifPro app.
3. Confirm on your phone: you see the account, the website and the browser before anything is sent.

SECURITY
• Paired browsers only: every login QR code is signed with this browser's own key. The phone rejects codes that do not come from a paired browser, so a QR code shown on a phishing page is refused.
• No secrets in the QR code: a photo of the code is useless. The phone and the extension agree on a one-time key (ECDH P-256), and credentials are encrypted end-to-end (AES-GCM).
• The server is only a relay: encrypted replies pass through a relay that cannot read them and deletes them after about one minute. Sessions expire after 90 seconds and work only once.
• Right site only: credentials are filled in only if the tab is still on the website the code was generated for.
• Minimal permissions: activeTab (the address of the current tab, when you click the extension) and scripting (filling in the login form after you confirm on your phone).
• No analytics, no ads, no tracking.

REQUIREMENTS
• The SeifPro Android app (latest version).
• Firefox 142 or newer.

Upgrading from version 1.0? Pair your browser again from the SeifPro app: older QR codes are no longer accepted.
