Very new to this and was reading that there were a couple of hacks short time ago and is recommended to  keep your bitcoins in offline computer. Here is my problem, a friend told me about bitcoin and I did open a wallet but it has been a few months and I lost where I stored my wallet password. I want to get going now and I see that I can have multiple wallets and of course, all but one offline. Only one to wheel and deal. Once I load some valuable coins then I will transfer to my offline wallets.

Do I need to download the software for creating wallets each time I create a wallet? If not, then how do I go to do my wallets.
