Please note that Yahoo no longer allows users to sign in to Yahoo using Facebook or Google. All Flickr or Fantasy Sports account holders must transition to a Yahoo account in order to continue accessing those services.
With so many changes taking place on Yahoo's platform, many users of Yahoo services (such as Flickr or Fantasy Football) are finding it difficult to understand if and how their various online IDs apply to different services. Yahoo account holders can access any of Yahoo's services by simply logging into the platform using their username and password, but the rules for non-Yahoo account holders are a bit more specific. This article will explain how to sign in to Yahoo services using a Facebook or Gmail account.
Log In to Yahoo Services with Facebook or Gmail
Head to Yahoo's Sign-in Helper, and enter your Google or Facebook ID into the Yahoo ID field. Then, click Submit. You may be prompted to enter a CAPTCHA code as an added security measure.
You will receive a password reset email at the ID entered on the sign-in page. Follow the link in the password reset email to create a new password.
You can sign in to your account by simply entering your non-Yahoo email address into the Yahoo ID field when logging in with your new password.
Once logged in, you will be able to upgrade your login ID to a Yahoo account by signing in to Yahoo Mail using your Facebook or Google ID.
