3rd Party cookies are blocked by default on Brave browser along with scripts and trackers, but this setting allows you to override that specifically for those social media sign-ins you would like to have working.

Facebook, Google, LinkedIn, advertisers and others were using these cookies for tracking you no matter where you went on the web (even if not logged into their services) but they will be discontinued (the 3rd party cookies that is) from 2021 apparently.

So browser fingerprinting is another thing that has emerged... Browser fingerprinting is a technique websites and advertisers used to track people without consent. The approach works by combining a large number of semi-identifiers together, to build a highly identifying value to identify users with.

Currently, Brave protects against fingerprinting by preventing third party sites from accessing functionality frequently used to fingerprint users. This includes highly identifying parts of the Canvas, Web Audio and WebGL APIs, among others. These default settings can be changed through Brave’s Shields interface, where users can disable these protections if needed, or also extend them to the first party. Brave prevents known fingerprinting scripts from being loaded, through the browser’s Shields protections.
