It is more than said and proven that passwords are the key that gives access to our information, and hence we give them so much importance. Today we use passwords to access our emails, the bank, social networks, online shopping sites … in short, we use passwords to access any site; and of course, as passwords must be robust, and on top of that we cannot use the same one for everything, so end up going crazy. That’s why some of us use password managers, mne-monics, etc. because otherwise it is impossible.
