What is a characteristic of a strong password?

A strong password typically uses a combination of characters, which can include uppercase letters, lowercase letters, numbers, and special symbols. This variety makes it significantly more difficult for someone to crack the password through guesswork or automated attacks. The rationale is that the more complex and varied the characters in a password, the larger the number of possible combinations, thereby increasing security.

Other options are considered weak elements of password creation. For instance, using only lowercase letters or a combination of just letters and numbers limits the complexity and makes it easier for attackers to exploit common patterns. Additionally, basing a password on easily guessable information, such as names or birthdays, greatly increases the risk of it being compromised, as these details can be often found or deduced by others.
