At present, an authentication token is generated by the app, and must be copied into the device’s code. This works great, as long as I’m the only person who needs to control my device. But let’s suppose that I want to give my Blynk-controlled device to a friend. In order for him to control the device with Blynk, I’d have to recompile and upload the code with my friend’s authentication token. Wouldn’t it be simpler if I could just give him the authentication token that’s already on the device? He pastes it INTO his app, and boom… he’s in control.
This would also work well for times when you’d like multiple versions of an interface for one device. I frequently want both a simplified, “user version” of a dashboard, as well as an experimental / testing version.
