There are two very common means that can put you at risk, username / password, most people are not aware of their privacy.
The password is an authentication key to obtain access to a site, it goes back to antiquity when the sentries asked for a secret code to allow the passage of another person. In the year of 1960 Fernando Corbató introduced the concept of computer password, this would help keep individual files private, it should be clarified that at that time the Universities shared their files on a single central computer, which allowed everyone to have full access to their contents.

The term password originates from Latin, Contra = contra and Signa = signal.

• In 1970 Robert Morris in Bell Labs invented the <hash> a process by which a string of characters is transformed into numerical code, that way the password is stored in an encrypted version.
As the years go by, the encryption system has improved, making it increasingly difficult to decipher a password, but why are so many attacks and accounts compromised? This is explained in a single word naivety many people believe that they will not be the victim of a computer attack because they may not be known characters, but the reality is different, the main attacks are made to:

• Clone identity.
• Obtain personal information.
• Extortion.
• Mass theft.

Let’s be honest, there is no super inviolable password, but that’s not why you should fall into the paranoia of putting black tape on the cameras of your devices, removing microphones, antennas and wearing a foil hull.
The password is subjected to an encryption process SHA, hash, ROT-13, there are several, but the encryption is public what really makes your password strong is the extension, the more characters you have the better. But do not trust since 2014 sequence 123456 has been the most used password and therefore the most insecure, here is a list of the worst existing passwords:
1. 123456
2. 123456789
3. qwerty
4. password
5. eggs1 (as in the movie)
6. 12344321
7. abc123
8.00000000
9. password1
10. 12345

But that’s not all, in most cases one can trust and use something personal, but this is not safe or recommended.

What your password should not have:
• Date of birth.
• Name of your pet.
• Phone number.
• ID.
• Car or clothing brand.
• Anniversary date.
• Favorite food, song or color.

Many black hackers or malicious people use this information to try to enter your accounts, mainly social networks, there are several methods to reinforce a password for example replace the <a> with a <4> but that everyone already knows that I can recommend replacing letters with numbers for example we will assume that your password is “secret”

Then for each space we press the number that is on it, so for the <S> it would be 2 twice, leaving 223444459 with that you get 9 characters, the minimum to consider accepting a password is 8 characters, but I have something better, and I do not mean the Passphrase that although they are safe they can sometimes betray us because we may use something very common from us.
I mean a password generator, an application that does the job for you, complex passwords of the number of characters you decide and best of all you don’t have to memorize because everything is stored in a virtual trunk, on the web there are several write password generator ”in your preferred search engine and hundreds of these will appear, here is an example of a password G2 @ bE $ C4a ^ 8x% qMzjiu $ e, 21 characters and has everything, numbers letters, uppercase, lowercase, everything To make a strong password, something else, update your passwords every so often, at 6 or 3 months.
• If you are going to connect to a public network and ask you to register use an alias and a disposable email of those that expire in 24 hours.
• Do not share your personal information with anyone.
• If you receive a message asking for access codes or personal documents, investigate the origin of that message before sharing.
• Avoid registering anywhere, especially those that offer cracked programs.

With all these recommendations you can already have more peace of mind, but it is not enough, with technology the important thing is caution and make responsible use of it, so far you already know how to connect in public spaces, generate passwords quite secure and that the sites of Piracy are dangerous, but that super password will be of no use if you let yourself be seduced by the tests you find on social networks, or games that predict your future, when you accept the terms of these you are also granting your personal data and allowing them to be used, the security key in the precaution and check the permissions and conditions of each web or app, without for example the flashlight asks for access to GPS or messages, it is better not to install.
