* Extension points that plugins might expose

h3. The plugin manager may have to deal with particular actions when a plugin is

* installation
* activation
* update
* deactivation
* un-installation

When a plugin is installed we may want to check the license and make users agree. We may also want to unpack the given plugin in a particular location.

Update `get_current_user` to receive the same token as before, but this time, using JWT tokens.

Decode the received token, verify it, and return the current user.

If the token is invalid, return an HTTP error right away.

{* ../../docs_src/security/tutorial004_an_py310.py hl[93:110] *}

## Update the `/token` *path operation* { #update-the-token-path-operation }

Create a `timedelta` with the expiration time of the token.

You can use `async` or regular functions.

**FastAPI** will do the right thing with each, the same as with normal dependencies.

If synchronous replication is configured above, replication is attempted right away prior to returning the PUT object response. In the event that the replication target is down, the `X-Amz-Replication-Status` is marked as `FAILED` and resynced with target when the scanner runs again.
