(Reuters) - Yahoo Inc will stop letting consumers access its various online services, including Fantasy Sports and photo-sharing site Flickr, by signing-in with their Facebook Inc or Google Inc credentials.
The change, which will be rolled out gradually according to a Yahoo spokeswoman, will require users to register for a Yahoo ID in order to use any of the Internet portal's services.
The move marks the latest change to Yahoo by Chief Executive Marissa Mayer, who is striving to spark fresh interest in the company's Web products and to revive its stagnant revenue.
"Yahoo is continually working on improving the user experience," the company said in a statement, noting that the new process "will allow us to offer the best personalized experience to everyone".
The first Yahoo service to require the new sign-in process is Yahoo Sports Tourney Pick'Em, a service focused on the NCAA college basketball tournament which begins later this month. News of the change to Yahoo's Tourney Pick'Em sign-in process was first reported by the technology blog Betanews.

The sign-in buttons for Facebook and Google will eventually be removed from all Yahoo properties, the Yahoo spokeswoman, though she declined to provide a timeframe.
