Protect users on this computer against password theft with a sign-in seal.

A sign-in seal is a secret message or photo that Yahoo! will display on this computer only. Look for it every time you sign in to make sure you’re on a genuine Yahoo! site. If the message, photo, or colors are different, you may have landed on a phishing site.

The sign-in seal that you create here will only appear on Yahoo! sign-in screens.

Ideea e similara certificatelor de email personalizate. Nu stiu daca se bazeaza pe un sistem complicat, sau poate fi usor de falsificat. oricum initiativa e laudabila, mai ales ca l-au facut colorat frumos, sa atraga userii :D. cand am mai multe detalii revin, de-abia acum am vazut cand am facut sign in la serviciile lor.
