Facebook revealed the information via a blog post(link is given below) written by CTO Mike Schroepfer. The blog post also mentioned about its privacy changes, which include restricting third-party app access and deleting phone call and text information that’s over a year old.
Besides this, Facebook said that it is ending a feature that lets users search for a profile using a phone number or personal email, and suggested that bad actors have abused the ability and taken information from personal profiles as a result.
Starting today, these privacy changes will now be implemented:
Third-party apps will no longer be able to access the member list of a group.
Third-party apps can no longer access personal information, such as names and profile photos etc.
Facebook is also limiting the use of the Pages API by requiring all future access to the entire access layer be approved by the company
Third-party apps can no longer ask for personal data like religious views, political affiliation, relationship status, custom friends list, education and work history, and activity on fitness, book reading, music listening etc.
Facebook will no longer let anyone input a user’s phone number or email address to find them on the social network.
