OpenID Connect (OIDC) is an identity layer built on top of the OAuth protocol, which provides a modern and intuitive Single Sign-on (SSO) experience to you and your end users. OIDC also improves the log in experience for mobile applications by enabling users to log in to ServiceNow applications using their social identity provider. For example, administrators can configure Single Sign-on with a third-party identity provider that supports OpenID Connect. Users then have the option to log in to your custom ServiceNow application using their identity provider credentials.

You can choose to use social identity providers like Google for your business-to-customer (B2C) users and enterprise identity providers like Okta, Microsoft Azure AD for your business-to-business users.
