How do I integrate OIDC in Angular?

Use angular-oauth2-oidc: config issuer/clientId, init service on APP_INITIALIZER, guard routes, callback path. Tokens auto for APIs.

OIDC vs OAuth2 for React SPAs?

OIDC adds ID tokens/claims on OAuth2 base. Use react-oidc-context for PKCE flow—secure, memory-safe.

Does OIDC work with Auth0 or Okta?

Yes, all major IdPs. Just match client settings: public SPA, PKCE, code flow.
