Lösenordsstyrka

Lösenordsstyrka refers to the measure of how difficult it is to guess or crack a password. A strong password is one that is hard for both humans and computers to compromise. Several factors contribute to a password's strength.

The length of a password is a primary determinant of its strength. Longer passwords are generally more secure because they offer a larger number of possible combinations for an attacker to try. For example, a password that is ten characters long has significantly more possibilities than one that is only six characters long.

Another critical factor is the complexity of the password, which refers to the variety of characters used. Passwords that include a mix of uppercase and lowercase letters, numbers, and special symbols (like !, @, #, $, %) are considerably stronger than those made up of only one type of character. This is because the character set available to an attacker is much larger when different character types are used.

Commonly used words, dictionary words, personal information such as names or birth dates, and sequential patterns (like "123456" or "qwerty") make passwords weak. Attackers often use dictionaries or brute-force attacks that systematically try common passwords and combinations. Therefore, avoiding these predictable elements is crucial for enhancing lösenordsstyrka.

To improve password strength, users are often advised to create unique passwords for different accounts. This prevents a breach on one service from compromising others. Password managers can assist in generating and storing strong, unique passwords, making it easier for users to maintain good security practices.
