When it comes to Facebook, you have little choice but be extra careful about what data you share on the platform. However, new reports claim that the data that you unknowingly share by simply following the process could be more dangerous for your online presence. If you are someone used to login to all online services with your Facebook account then it would be a good idea to stop doing so.
So, whether you are playing Call of Duty Mobile or have signed in to your Tinder account with your Facebook ID, it is generally a good idea to stop doing so. This is because “when a user grants a website access to their social media profile, they are not only trusting that website, but also third parties embedded on that site,” claims a new research report by Princeton University.
For most Facebook users, using the same login ID for other services is the most common thing to do. But it is a mistake that you need to stop doing. The safest bet is to create an entirely different secondary email ID which is not linked to your primary ID and then use it for signing in to other services.
While bigger platforms and websites might offer less worries, it is the smaller websites and apps that you login using your Facebook ID that is more concerning. Explaining the risk, the report claimed, “The user ID collected through the Facebook API is specific to the website (or the “application” in Facebook’s terminology), which would limit the potential for cross-site tracking. But these app-scoped user IDs can be used to retrieve the global Facebook ID, user’s profile photo, and other public profile information, which can be used to identify and track users across websites and devices.”
Another major risk associated with using Facebook to login to services is targeted advertising. Targeted advertisements can be used to sell wrong products or even spread misinformation. The report claimed, “Some third parties use the Facebook Login feature to authenticate users across many websites: Disqus, a commenting widget, is a popular example. However, hidden third-party trackers can also use Facebook Login to deanonymize users for targeted advertising. This is a privacy violation, as it is unexpected and users are unaware of it.”
