Can I have two Fitbit devices on the same account?

I just received my second Fitbit.  How might I link the old and the new?

If you mean keeping you history data, just use the same account to add the new device.

If you mean to use both devices, cannot do unless your previous one was a very old model.

Thanks, Do I simply start wearing the new one, hoping Firbit will
accommodate me?

First, do a sync with old device to make sure all your data on it gets to the Fitbit database before removing that device.

Then same way you added first one.  On phone app,

Profile pic > Set up a Device > Select your new device

It will say something like 'I see you already have a xxx connected.  Do you want to replace this?'  Answer yes, and it will remove old tracker and continue with setting up new one.  On completion your data will look continuous with previous tracker.  It any trouble setting up new one, might help to move old tracker (and any other bluetooth devices) to another room to avoid bluetooth interference.
