Re: The only problem
I guess the idea is that you only really have one file that lives in Dropbox or somewhere - you don't 'sync' the file as such.
But then you open a whole other can of security worms - picking a secure cloud storage platform that you trust. I certainly wouldn't trust Dropbox with anything more than important than cat pictures!
I think this story shows how good LastPass actually is. They accepted the fault and worked with the guy to fix it then admitted the problem. How many companies do we see burying their head in the sand when these problems are found? Microsoft - I'm looking at you!
