Facebook now lets you bulk remove third-party apps, and any and all posts those apps may have published on your behalf, a welcome privacy change that should make it easier to strip access to your profile from services you no longer use. The change, precipitated by the ongoing Cambridge Analytica data privacy scandal, is part of a series of sudden changes Facebook is making to mitigate fallout from the revelation that third-party developers have had generous access to users’ data and could use it in ways Facebook had little to no control over. Facebook confirmed the bulk removal option to TechCrunch today, after The Next Web’s Matt Navarra publicly commented on the policy change on Twitter.

Now, when you go to the Apps portion of your Facebook settings, you can click on any number of third-party apps with direct access to your data and remove them in bulk. Prior to the change, you had to do so on an app-by-app basis, making the process cumbersome and time-consuming. The changes are part of Facebook’s larger efforts to make app access easier to manage and understand, as outlined two weeks ago alongside Facebook’s decision to more broadly limit app developers’ access to user data.
