The all-new Yahoo! sign-in seal

Came across this new security feature when logging into Yahoo! today. It's what they call a sign-in seal to prevent phishing attacks. If it takes off as planned, we may see similar security measures across the web on other websites. Kudos to Yahoo! for making the first move in this space.

Here's an extract from their help guide:

A sign-in seal is a secret message or image that you select to help protect your account from phishing -- a scam that tries to steal your password or personal information by spoofing a legitimate web site.

When you create a sign-in seal for your computer, you can be sure you're on a legitimate Yahoo! site each time you use this computer to sign in to Yahoo!. Just look for the custom text or image you set up on this computer. If it's not there, you might have landed on a "spoofed" site.

Your sign-in seal is saved on the computer you created it on. If you use more than one computer or browser, you may want to create a sign-in seal for each one.
