Strong passwords are a fundamental aspect of digital security, and their effectiveness depends primarily on their length and randomness. According to OWASP ASVS 4.0 guidelines, a secure password should be at least 12 characters long. This baseline significantly increases the time and computational resources required to break a password using brute-force or dictionary attacks, making such attempts largely impractical.

However, relying solely on the minimum recommended length may not provide optimal protection, especially in high-risk environments. To enhance security further, it is advisable to use passwords that are at least 16 characters long. Longer passwords exponentially increase the number of possible combinations, thus improving resistance to various attack methods.

In addition to length, incorporating a mix of uppercase and lowercase letters, digits, and special characters adds complexity and unpredictability. This makes passwords more resistant to pattern recognition and rule-based cracking techniques. Importantly, such passwords should be generated randomly rather than based on memorable phrases, as human-chosen passwords tend to follow predictable structures.

Using a password manager is strongly recommended to safely generate, store, and retrieve long, complex passwords. This ensures strong authentication practices without sacrificing usability or requiring users to memorize high-entropy strings.
