## GraphQL for B2B course authentication updates

The GraphQL for B2B course now covers authentication across both the BigCommerce GraphQL Storefront API and the B2B GraphQL API.

* **Two GraphQL APIs** — the course overview and introduction clarify that both the B2B GraphQL API and the standard GraphQL Storefront API support B2B operations.
* **Authentication flows** — the Authentication lesson walks through logging in with each API, including customer context, tokens, and exchanging a Storefront API session for a B2B token.
* **Course prerequisite** — recommends completing the GraphQL Storefront API course and links to it.
