Yahoosigninseal

I noticed that Yahoo has started offering personalized anti-phishing seals. The seals are linked to each computer, not Yahoo! IDs. Looks like they started offering the service back in September.

How does a sign-in seal protect me?

A sign-in seal is a secret between the computer you set it up on and Yahoo!. So when you sign in to Yahoo! from this computer, your sign-in seal tells you that you’re seeing a genuine Yahoo! site, not a phishing site.

Why do I have to set up a seal on each computer I use?

Your sign-in seal is associated with your computer, not your ID. It is a convenient way to instantly recognize a genuine Yahoo! sign-in page and be sure that you’re not on a page created by fraudsters attempting to steal your Yahoo! ID and password. Because we associate your sign-in seal with your computer, after you create a seal, there are no additional steps to signing in. Even if a phisher knows or guesses your ID or other personal information, they cannot use it to discover your sign-in seal. Note: Yahoo! will never ask for your Yahoo! ID or password in order to set up or display your sign-in seal.

I was going to show what the final seal looks like but that would be counter-productive to say the least.
