It would be useful if there existed a way to export some kind of temporal password from idena application. You could export it one time let's say right after a validation and then use it to login in multiple services while your node is offline. Such temporal passwords should work only during one epoch and then must be replaced with new ones.
Automatic login feature to different web services can also be implemented via a browser extention.
Or you can have an app on smartphone with this password imported and then you need to scan a QR-code with this app in order to login to a service. Something like web.whatsapp.com works.
