Openid connect

Definition

OpenID Connect is an authentication layer built on top of the OAuth 2.0 protocol, allowing clients to verify the identity of users based on the authentication performed by an authorization server. It enables applications to securely access user information and perform single sign-on (SSO) across different services. OpenID Connect's standardized approach enhances interoperability among various applications in the financial services sector, facilitating open banking and API integration.
