The fact that this is **standard Python** means that you will still get the **best possible developer experience** in your editor, with the tools you use to analyze and refactor your code, etc. ✨

And also that your code will be very compatible with many other Python tools and libraries. 🚀

FastAPI provides several tools for each of these security schemes in the `fastapi.security` module that simplify using these security mechanisms.

In the next chapters you will see how to add security to your API using those tools provided by **FastAPI**.

   *       proxy will be passed to the method. It's possible that the method body expects an
   *       instance method of the passed-in proxy to be of a certain value yet the proxy isn't aware
   *       of the assumption, in which case the equality check before and after serialization will
   *       fail.
   *   <li>If the constructor or factory method takes a parameter that {@link

     * will be used. If a non-null list is returned, it will be used instead of the
     * session's repositories, allowing for request-specific repository configuration.
     *
     * <p>The returned list should not contain duplicate repositories (based on their
     * equality) or null entries, as these will cause validation failures when the
     * request is processed.

You can "star" FastAPI in GitHub (clicking the star button at the top right): <a href="https://github.com/fastapi/fastapi" class="external-link" target="_blank">https://github.com/fastapi/fastapi</a>. ⭐️

By adding a star, other users will be able to find it more easily and see that it has been already useful for others.

After a week, the token will be expired and the user will not be authorized and will have to sign in again to get a new token. And if the user (or a third party) tried to modify the token to change the expiration, you would be able to discover it, because the signatures would not match.
