-pubkey auth flows require that a callback be triggered on success as part of the authentication flow. For this reason, it may be that the device scanning the QR (e.g. a mobile) is not the same device that's trying to authenticate (e.g. a desktop). So, we require session storage to persist some data and make it available across devices and ensure it's available when the callback is triggered.
