# Tokens

Authgear uses industry-standard tokens to manage user authentication and authorization. This section covers the different types of tokens, their structure, and how to use them in your applications.

## Token Types

Authgear provides several types of tokens for different purposes:

* **JWT Access Tokens**: Used for authorizing API calls and accessing protected resources
* **M2M Tokens**: They are JWT access token issued to M2M applications for authorizing API calls and accessing protected resources.
* **Refresh Tokens**: Used to obtain new access tokens when they expire
* **ID Tokens**: Contain user identity information for OpenID Connect flows
