# Start Here Fanatics ID supports two authentication options as a mechanism to accessing our ecosystem. Typically tenants will integrate with our [single sign-on](https://en.wikipedia.org/wiki/Single_sign-on) website and access our APIs with tokens that represent the user that logged in. Additionally we do support server to server authentication that will result in tokens that do not represent a specific user. Please work with the Fan EcoSystem team to identify which type of integration you should implement based on your use case. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
