Recently many people who bought bitcoin years ago find themselves sitting on an untouchable bounty. Those lucky guys who purchased or mined just a few bitcoins at the start of the age of cryptocurrency nowadays can boast about their savings. However, some of them are now in a painful limbo，because they can't remember the complex security passwords needed to get to their bitcoin wallet. Unlike a bank, bitcoin has no central hotline to call for a reset. This is really a bad thing，it's like forgetting a bank account password, but there's no bank to call to reset it. That money is lost forever. That might be a lot of money at todays exchange rate.
Actyally, this bad thing happened to me last year, and my friend recommend this website：
http://recovermybtc.com/ to me，she said she has retrieved her bitcoin wallet password through it，and I download this software，it really works after I used it，and you need to pay some service fee to them, but it's not high.Somebody who lost their bitcoin password can make a try, good luck.
I am not sure about the website for now so I am waiting until someone else proves it really works. This can be one of those too good to be true but I also do hope it really works because many of here can experience that incident. But to avoid forgetting your password, always keep a copy to you, both printed and digital and make sure that those info are secured. Play safe and success is on your way.
