**Type:** Tutorial

## Summary

The updated Okta Angular SDK introduces fully standalone architecture, eliminating NgModules and wrapper functions in favor of standalone providers and functional guards. In an Angular v22 sample project, authentication is configured with the provideOktaAuth function without requiring a custom backend. Route security utilizes functional guards, while user and group data fetch flows are handled using rxResource alongside signal inputs. To support dynamic environments without requiring rebuilds or redeployments, the setup implements runtime configuration loading via provideAppInitializer and OktaAuthConfigService. Security is further bolstered by binding access tokens to browser key pairs using Demonstrating Proof of Possession alongside OAuth 2.1 and OpenID Connect protocols.

## Context

Legacy Angular SDK integrations relied on NgModules, importProvidersFrom wrappers, and static compile-time configurations that required full application rebuilds whenever settings like client IDs or issuers changed.

## Approach / What changed

Integrate the standalone Okta Angular SDK into an Angular v22 application using provideOktaAuth, functional route guards, rxResource with signal inputs, and runtime configuration initialization via provideAppInitializer.

## Takeaways

- The updated Okta Angular SDK fully adopts standalone APIs, replacing NgModules with provideOktaAuth and class guards with plain functions.
- Runtime configuration loading can be implemented using provideAppInitializer and OktaAuthConfigService, allowing issuer and client ID changes without application rebuilds.
- Calls to inject() inside an asynchronous initializer function must execute before the first await to remain within Angular's injection context.
