As announced earlier today, we'll begin rolling out a feature that gives people more transparency and control over the data other apps and websites share with us. We believe that giving people transparency and control is good for businesses and developers as people will be more informed on how their information is used and feel better about the products they interact with online.
When using this feature, people will be able to see a list of apps and websites they’ve visited that use Facebook business and/or developer tools such as the Facebook pixel, SDK and APIs.
As this feature rolls out, it may impact Facebook Login. When people exercise control to clear their off-Facebook activity or disconnect future activity, their user access tokens for third-party apps or websites where they used Facebook Login will be invalidated, and they may be logged out of the app or website. When they do log back in, the app or website will receive the same App Scoped ID they previously had to preserve continuity.
To help developers prepare for the launch of this feature, we’re providing our developer community with updated implementation best practices and guidance.
