I have a dumb question... I - finally - got myself a cell phone (at 24.9% off with bitcoin thanks to https://purse.io/?_r=XClu2O). I'd like to enable a notification whenever my rig is not responding on Leaserig, but can't figure out how to do this. Do I need to enable 2FA on Leaserig? I'd prefer not to be getting notified every time I get an email, just the rig-not-responding notifications.
