# Trusted Auth Tokens

> Trusted Auth Tokens for the B2BIdentityProvider component

If your project is using [Trusted Auth Tokens](/multi-tenant-auth/authentication/trusted-auth-tokens/overview), they can be provided to the component as well. When `trustedAuthTokenParams` are supplied, the component will exchange the provided token for a session and automatically log the user in before starting the authorization flow.

To see all authentication and customization options, see the [UI configuration props](./configuration).
