alex_herrero Dunno, I only switched over to Nova Prime a few months back but I haven't been asked to reconfirm yet. Honestly I don't think you'll be asked to reconfirm unless you reinstall the app, and persnonally I wouldn't even worry too much if I had to grand network access for 2 min every half year or so.
Nova I a great launcher and I haven't looked back since I switched over. You'll get 90% of the way the free version, Only paid features I really missed was notification badges and custom swipe shortcuts.
