Yahoo is testing a new security feature that lets users customize their login page, a measure designed to thwart information-thieving phishing scams.

The feature requires people to create a unique “sign-in seal” on a specific PC. This seal—a text message or photo—will be displayed on the Yahoo login page when visited with that computer, according to a description of the feature on Yahoo’s Web site.
