Can someone fill me in on how these password apps work? I understand you have one master pw then the app creates random pw for everything you need. So does this mean if my main pw is hacked then everything is hacked? this seems kind of dangerous but I guess no more dangerous than remembering other pws. And how does it work in ios? Does it prefill pws or do i have to toggle through and find it each time? And how about integration with PCs and macs? I use chrome on my home pc alot too so it'd be nice to have it cross platform. I guess I've just never understood fully how these pw programs work and am looking for some first hand knowledge.
