What should a strong password include?

A strong password should include a combination of uppercase letters, lowercase letters, numbers, and symbols. This mix enhances security by making it significantly harder for unauthorized users to guess or crack the password. Each element adds complexity: uppercase letters increase the character variety, lowercase letters provide additional combinations, numbers contribute numerical variability, and symbols introduce special characters that further complicate the password.

This approach to password creation is supported by cybersecurity best practices, which emphasize that the more diverse the character set used, the stronger and more resilient the password will be against attacks such as brute force attempts or dictionary attacks. A password that only contains lowercase letters or just a phrase would lack this complexity, making it relatively easier for attackers to compromise. Similarly, using only numbers and symbols does not provide the ideal variation needed for optimal security.
