# Welcome to Authlete

**Authlete is an API-first service where every aspect of the platform is configurable via API.** This documentation provides comprehensive guides and API references to help you build secure OAuth 2.0 and OpenID Connect functionality in your service.

## What is Authlete?

Authlete provides a set of web APIs that enable developers to implement full-featured OAuth 2.0 and OpenID Connect (OIDC) authorization servers. Instead of building a complex authorization mechanism from scratch, you can leverage Authlete to handle:

* **OAuth/OIDC Protocol Processing**: Support for various flows, profiles, and extensions, including Authorization Code, Client Credentials, Device Flow, FAPI, and OID4VCI.
* **Token Management**: Full control over token issuance, validation, and revocation for all artifacts (such as access/refresh tokens, authorization codes, and request URIs).
* **Client Management**: Secure registration of OAuth clients and OIDC Relying Parties (RPs), including client credentials, redirect URIs, and JWKS.
* **Service Management**: Custom configuration of authorization servers, including grant types, scopes, and claims.
