Forget Password

It's a bad day today, due to some personal reason. It's been a long time since I open my laptop. Because my wifi connection is very slow, that's why I just use my cellphone in every transaction that I do. I think it's more than 6 months since I last used it. And now that I'm trying to log in with my user account, I forgot my password! I start to guess from 9am up to 1 pm but still I can't remember it anymore. The good thing is my daughter whos the admin of that account tell me her password, so I can log in with her account. But unfortunately I don't know how to retrieve my password, and all the files that I had there.
