NEW YORK (TheStreet) - Yahoo! (YHOO) is sending a message to its users: we want you on our platform, not theirs.
The Sunnyvale, Calif.-based Internet portal will be doing away with letting users sign in for various services with their Facebook (FB) or Google (GOOG) account information, as reported by Reuters and confirmed by TheStreet.
Those services include Yahoo! Fantasy Sports and its photo-sharing site Flickr. Users will be required to register for or sign in using their Yahoo ID.
"Yahoo is continually working on improving the user experience, which includes our sign-in process for Yahoo Sports Tourney Pick'Em. This new process, which now asks users to sign in with a Yahoo username, will allow us to offer the best personalized experience to everyone," according to a company statement.
The company plans to gradually roll out the change across its platforms and services, spokeswoman Lauren Whitehouse wrote in an email.
The updated sign-in process will provide a streamlined sign-in experience; a single account and password for all Yahoo products, across devices; faster customer support and account assistance and easier password recovery, Whitehouse notes. The sign-in buttons for Facebook and Google will eventually be removed from the user experience.
The first service to require a Yahoo! user ID will be Yahoo Sports Tourney Pick'Em, a service focused on this month's NCAA college basketball tournament. The change will be effective on Monday, Reuters noted.
