has admitted providing dozens of tech companies with special access to user data after publicly saying it restricted such access in 2015.
Facebook continued sharing information with 61 hardware and software makers after it said it discontinued the practice in May 2015, the social networking giant acknowledged in 747 pages of documents delivered to Congress late Friday. The documents were in response to hundreds of questions posed to Facebook CEO
by members of Congress in April.
Facebook said it granted a special "one-time" six-month extension to companies that ranged from
"We engaged companies to build integrations for a variety of devices,
and other products where we and our partners wanted to offer people a way to receive Facebook or Facebook experiences," the company said in the documents. "These integrations were built by our partners, for our users, but approved by Facebook."
Facebook's documents also said it had discovered that five other companies "theoretically could have accessed limited friends' data" as a result of a beta test.
Facebook said in the documents it has ended 38 of the partnerships and plans to discontinue seven more by the end of July.

The disclosure was part of Facebook's second attempt to address questions posed to Zuckerberg in April by members of the House Energy and Commerce Committee. In June, the social network released its written responses to some of the committee's questions, many of which Zuckerberg responded to during that hearing by saying he'd have his team "get back to" lawmakers with answers.
Zuckerberg's testimony before both the Senate and House in April came as the social network deal with a scandal involving Cambridge Analytica, a digital consultancy that had ties to the Trump presidential campaign. Cambridge Analytica improperly accessed personal information on up to 87 million Facebook users, prompting a backlash that raised questions about whether Facebook can be trusted to protect the personal information of its 2 billion users.
The company has also been in the hot seat for not doing enough to prevent abuse from Russian trolls that posted misinformation and divisive content on the platform. The Russian activity was part of a program to meddle in the US presidential election and sow discord among voters.
The controversy erupted in June when the New York Times reported that Facebook had agreements to provide access to large amounts of user data to at least 60 different device makers -- including companies like
In a test, a New York Times reporter logged into Facebook using a 2013 BlackBerry device, using an account with roughly 550 friends, monitoring the data requested and received. Through a BlackBerry app called The Hub, the device was able to acquire "identifying information" for up to 295,000 Facebook users.
Facebook didn't immediately respond to a request for comment but has previously said it's taking actions to make sure the Cambridge Analytica data exploit doesn't happen again. Zuckerberg said Facebook will investigate all apps that have access to large amounts of data, and restrict developers' data access even further.
