They say security is the most important and I use to take the recommendations very seriously. All my devices, the applications, the social networks, the e-mails, the bank accounts, have their security keys, of those that mix numbers and letters, capitals and smalls; and the most delicate, those, those contain some special character too. But the important the good keys are, the more it is to protect them well, that’s why I developed an infallible protection system, a hieroglyph only decipherable with an unique sequence of deductions, with a mental map... now I only have to remember which one.
