# Current Customer

Identify signed-in customers securely by requesting and decoding a BigCommerce-generated JWT.

## Authentication

Authentication consists of two parts; first, send the client ID of an app-level API account as a query parameter with your request. No scopes are required. When you receive a response, use the same API account's client secret to decode the JWT that BigCommerce returns.

[Learn more about the Current Customer API](/developer/docs/storefront/guides/customer-authentication/current-customer).

For info about API accounts, see our [Guide to API accounts](/developer/docs/overview/api-fundamentals/api-accounts#api-accounts).
