About ShieldSign
π‘οΈ ShieldSign β 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.
--------------------------------------------------------------------------
π― 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:
π "Can I type my password here?"
With ShieldSign, the answer is visual, immediate and reliable.
--------------------------------------------------------------------------
β¨ What ShieldSign does for you
-------------------------------
βοΈ Automatically identifies login pages
As soon as a site contains a password field, ShieldSign checks the domain.
βοΈ 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.
βοΈ 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
βοΈ 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.
βοΈ 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.
--------------------------------------------------------------------------
π 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.
