OpenID Insights

What is OpenID?

OpenID is an open standard and decentralized authentication protocol. It allows users to be authenticated by a third-party service, eliminating the need to create new accounts and passwords for every website they visit. Users can authenticate using their existing accounts with OpenID providers like Google or Microsoft, and then grant websites permission to access their profile information. This simplifies the login process and enhances security by reducing the number of passwords a user needs to manage.
