October marks Yahoo Mail’s 18th anniversary and to celebrate this occasion Yahoo introduced a new Yahoo Mail app that comes with a number of new features, including smarter search, contacts management, rich compose, multiple mailbox support, and password-free sign-in. Taking into account that most people have an email account from more than one email service provide, Yahoo designed its new email app to allow multiple mailbox log in. You can now connect and manage your email accounts from Outloook.com, Hotmail, and AOL Mail right from the Yahoo Mail app on mobile and desktop. Once connected to the email accounts, you can access Yahoo Mail’s features across all your mailboxes. “Email is the most prevalent way people communicate online. However, what we want from our inbox is evolving. Mobile use requires a faster and smarter inbox,” said Yahoo Senior Vice President of Communication Products Jeff Bonforte. “Both of these needs are at the center of our new app.” The new Yahoo Mail app also introduces the Yahoo Account Key—a more secure and simpler alternative to the old password. Simplifying the sign-in process, this new feature will let you access a Yahoo account with just the tap of a button. “Passwords are difficult to remember and secondary sign-in verification is inconvenient and confusing,” said Yahoo Vice President of Product Management Dylan Casey. “Earlier this year we launched on-demand passwords using an SMS code. We’re now taking a major leap towards a password-free future with the launch of Yahoo Account Key, which uses push notifications to give users simple and secure access using their mobile device.” The new Yahoo Mail app is already available for download for iOS and Android devices from the Apple App Store and Google Play Store, respectively. The multiple mailboxes feature for the mobile app and the Yahoo Account Key are already available, while the desktop experience is available in the U.S. and will be available soon to users outside U.S.
