Yahoo! have expanded & refreshed their programming tools offered to developers to build enhancements for your mailbox. With new interface, trusted companies can now build features that help you do more with messages in your Yahoo! Mail account, and do so in a way that keeps you in control. Here’s how it works: Say a company builds a tool that sends users a text message alert whenever their boss e-mails them. With the new tools we’re announcing, Yahoo! Mail users who’re interested in this service can securely grant access to that company without sharing their password (which would be a definite no-no); because they don’t have to share their password, they can also easily revoke access if they change their mind. We’ve even added the ability to limit whether the company can view whole messages or just selected bits like the Subject line. With these enhancements, it’s easier than ever for companies to build new features, and we’re all excited to see what new inventions they’ll build with this service. Developers, start your engines!,” notes Yahoo!.
