# Tenant-level elements Each tenant application will have three security elements associated with it: * client\_id * client\_secret * client\_app\_key They do not expire, but can be refreshed using the developer's portal. As you'll notice in the developer's guide, a user session ends with receiving a `temp_token`. The reason we're not sending the `access_token` directly is that we designed the session flow to be developed entirely in a web/mobile context. This choice also facilitates the future development of client SDKs. Hence the middleware returns a temporary token that needs to be sent to your backend first and then exchanged for the final `access_token` via a server-to-Finqware API call. As a side note: we're also considering introducing a callback endpoint as an option. Following the end of a session, Finqware would call an API endpoint provided by your server for the token exchange. --- # 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. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.finqware.com/overview/security-model/tenant-level-elements.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
