What is a common characteristic of strong passwords?

A common characteristic of strong passwords is that they contain at least one special character. Including special characters (like @, #, $, %, etc.) adds complexity to the password, making it more difficult for unauthorized users to guess or crack it. This complexity helps protect against various attack methods, such as brute force attacks, where a hacker tries all possible combinations to gain access.

A strong password typically combines uppercase and lowercase letters, numbers, and special characters. This combination increases the number of possible variations, thereby enhancing security. While memorability is important for users to manage their passwords, prioritizing complexity and uniqueness is crucial for protecting sensitive information. Using the same password across multiple accounts or relying on letters only significantly reduces security, making it easier for attackers to access personal data.
