🛡️ ShieldSign — The simplest way to know where you can enter your password Knowing if a login page is real or fake should be obvious. Today, it's no longer the case: phishing pages have become indistinguishable to the naked eye. ShieldSign solves this problem. The extension automatically validates safe login pages and displays a clear, visible banner that's impossible to imitate. If ShieldSign doesn't confirm the page, don't type your password. 🎯 Why is this really useful? Because today we get tricked not by carelessness, but because a fake site can be perfectly identical to the real one. The only important question becomes: 👉 "Can I type my password here?" With ShieldSign, the answer is visual, immediate and reliable. ✨ What ShieldSign does for you ✔️ Automatically identifies login pages As soon as a site contains a password field, ShieldSign checks the domain. ✔️ Displays an impossible to imitate validation banner 3 security modes:

Discreet badge
Personal keyword known only to you
Random code changing with each visit (recommended)

An attacker cannot reproduce this code or keyword. Even a perfect copy of the page will be unmasked in a second. ✔️ Works with lists: community, personal, enterprise

A community list of trusted domains
Your own favorite domains
Enterprise option: a list pushed by your organization, to secure internal access

✔️ Automatically adds your legitimate sites Every time you log in to a new site, ShieldSign can offer to save it. You have nothing to manage: the extension learns with you. ✔️ 100% local, 100% private

No data sent to a server.
No tracking.
The list of sites you use stays in your browser, only as URLs.

🔒 Why is it safer than an HTTPS padlock? Because all modern phishing sites also have a padlock. Because "looking at the URL" is no longer realistic: tired, rushed, stressed... humans get tricked. ShieldSign gives you an external visual marker, safe, constant, reliable. You no longer wonder:

"Is this the right site?" You simply look: Is the banner there? Then it's good.
