Final answer:
It is false that a strong password must contain no more than seven characteristics; strong passwords should be at least seven characters long, and often longer, with a mix of different types of characters.
Step-by-step explanation:
The statement that a strong password must contain no more than seven characteristics is false. In the context of cybersecurity, a strong password typically is at least seven characters long but often much longer to ensure greater security. In fact, many security experts recommend passwords that are a minimum of 12 to 15 characters in length. A strong password also includes a mix of uppercase and lowercase letters, numbers, and special symbols. The length and complexity of a password make it more difficult to crack, thus providing better protection for user data.
