Important information for AT&T customers and their Yahoo experience
You may have seen reports that there will be changes for users who use AT&T credentials to sign in to Yahoo properties, including properties like Sports and Finance. This does not impact your AT&T Mail accounts (including @att.net, @sbcglobal.net, @bellsouth.net, etc.). You can continue to use them as you always have and will always be able to access your AT&T email from att.net. However, going forward, AT&T customers accessing Yahoo properties may notice changes in the sign-in experience.
If you would like more information on how these changes impact your Yahoo access, please visit this AT&T support article.
