Which of the following might indicate one of your account passwords is too weak?

A password containing fewer than 12 characters may indicate that it is too weak. Strong passwords typically have a minimum length of 12 characters, which greatly increases the number of possible combinations and makes them more resistant to brute-force attacks. Password strength is not only determined by the type of characters used but also significantly by their length. Shorter passwords can be more easily guessed or cracked through various means, making them vulnerable.

While the other options represent good practices for creating strong passwords—such as using a mix of uppercase and lowercase letters, including special characters, and incorporating numbers—these elements alone do not guarantee strength if the overall length is insufficient. A longer password with a combination of these features is generally recommended for enhanced security.
