The challenge

One problem that we all have these days is remembering passwords. We have passwords for everything: websites, phones, cards, bank accounts, and so on. The amount of information we have to memorize is just too much, so many people end up using the same password over and over again. This is very bad, of course, so at some point, tools were invented to alleviate this problem. One of these tools is called KeepassX, and basically it works like this: you start the software by setting up a special password called master password. Once inside, you store a record for each password you need to memorize, for example, your e-mail account, the bank website, credit card information, and so on. When you close the software, it encrypts the database used to store all that information, so that the data can only be accessed by the owner of the master password. Therefore, kind of in a Lord of The Rings fashion, by just owning one password, you rule them all.
