ShieldSign di SingeQuantique

🛡️ 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.
