I. error
Use of personal data Most people use the names and dates of birth of children or their loved ones, the names of pets or the names of sports teams. But special programs used by hackers automatically try combinations of data that can be found out about a given user, most often on social networks.
ADVICE: “The only safe password is a password with random or seemingly random sets of characters,” says Ondřej Ševeček from the Gopas computer school.
II. error
Recognizable password patterns like 1q2W3e4R or 0m9n8B may seem secure, but only until you look at the keyboard. There is also a problem with replacing letters with numbers, when some are directly offered for replacement – 3 for e, 0 for O, 6 for C, etc. Although the password n3zap0M3n looks complicated, it is relatively easy to detect.
TIP: To create a strong password, the random string of letters and numbers must be truly random.
III. error
The same for different services It is not enough to have several strong passwords for different types of services and use them repeatedly. It is a problem to keep track of which systems you enter which passwords. Just panic and enter all possible passwords on public WiFi for nothing. Capturing such a password by a hacker means exposing a number of systems.
ADVICE: Using the same passwords for access to the e-shop as well as to the company e-mail or to the bank is quite risky.
IV. error
Too few characters Using only five or six-digit passwords is not secure, it can be detected by programs that try combinations of characters. A long and easy to remember password with at least 12 characters is safe.
TIP: You can create long passwords as a sentence or by combining several words. Use an occasional capital letter, a number here or there, or a special character.
