`default_url` will get the user if the request is authenticated. If you aren’t seeing that, my guess is that it’s because default\_url is being called before the user is authenticated, and is being _persisted_ through login, redirects via the `?next` url parameter, so the value doesn’t get recomputed after authentication has completed.

Try sending unauthenticated users directly to /hub/login, which will result in computing default\_url again after successful login, for example:

```python
def default_url(handler):
    user = handler.current_user
    if not user:
        # not logged in, send to login, no ?next
        # that way, default_url will be called again after successful login
        return handler.get_login_url()
    if "admin-ui" in handler.expanded_scopes:
        # has permission to view the admin page, send there
        return handler.base_url + "hub/admin"
    else:
        # regular user, send to spawn page
        # (which redirects to running user if it's running)
        # this is the default default URL
        return handler.base_url + "hub/spawn"

c.JupyterHub.default_url = default_url

```
