OpenID Connect (OIDC)
Optimizely Graph supports OIDC and uses the Opti ID provider by default.
Optimizely Graph uses OpenID Connect (OIDC) to authenticate API requests with industry-standard token-based identity. Opti ID is the default OIDC provider, which lets you reuse Optimizely single sign-on (SSO) credentials, enforce role-based access, and federate with other identity providers when your organization requires them.
See the documentation on the Overview of Opti ID and Get started with Opti ID for information.
