Why password strength matters

Password strength measures how effective a password is against guessing or brute-force attacks. It estimates how many tries an attacker who has no prior knowledge would need to guess your password correctly. Strength is determined by password length, the variety of characters used, and its unpredictability.

Having strong passwords lowers the risk of a security crack or breach. Many systems limit repeated attempts or add time-outs after failed logins, but if password data is stolen from a breached system, weak passwords may still be exposed. Strong, unique passwords remain your best defense.

FAQ

Longer passwords generally resist brute-force attacks more effectively, but length alone isn’t enough. Use a mix of uppercase, lowercase, numbers, and symbols to increase complexity and entropy.

Spaces can improve complexity and make passphrases easier to remember. Ensure your password still includes other character types and is not a common phrase.
