Protect your Yahoo account from password phishing

A sign-in seal is a secret message or image that you select to help protect your account from fraud such as password phishing (Phishing is when a fraudster sends you an email or link, claiming to be from a legitimate company. They'll often send you to a fake website they've created, and trick you into entering your password and personal information. You're then an easy target for account theft.)

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 your computer to sign in to Yahoo!. You’ll see the text or image you set up on your 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 log in from a different computer, you won't see the sign-in seal. If you use more than one computer or browser, you can choose to create a sign-in seal for each one.
If you don’t see your sign-in seal on the Sign-In page, the webpage you've opened is probably a fake Yahoo! Sign-In page. If this happens, please report the webpage immediately!
Important: Don't create a sign-in seal on a computer you share with strangers, such as those in libraries, Internet cafes, and other public places.
