# Configuration

SAML.to is a bridge between Identity Providers (such as GitHub) and Service Providers (such as AWS) using the SAML 2.0 Protocol.

By logging into an Identity Provider, a long (or short)-lived token is generated and used to identify Users and Repositories that want to exchange for a short-lived token at Service Providers.

The following pages details configuration options for[ Identity Providers](https://docs.saml.to/configuration/identity-providers) and [Service Providers](https://docs.saml.to/configuration/service-providers).
