I think you’re mistaken, but I could be wrong. I’ll let others chime in.
We use Xano auth and it works just fine, whether you hard refresh, quit the browser, etc.
If you hard refresh and the auth token is erased, it sounds like you’re saving and retrieving the auth token somewhere else other than saving it as a cookie.
