FedCM aims to replace third-party-cookie social login
The article explains that legacy social login flows such as "Sign in with Google" depend on third-party cookies and are increasingly fragile as browsers block or phase them out. It presents FedCM (Federated Credential Management) as a browser-mediated standard that preserves federated sign-in without cross-site tracking, using a native consent prompt and explicit user approval.
