Why You Need a Password Generator
Humans are remarkably bad at creating truly random passwords. We gravitate toward dictionary words, predictable substitutions (@ for a, 3 for e), and patterns that feel random but are easily guessed by automated cracking tools. A password generator removes human bias entirely, producing strings that have maximum entropy per character.
Password Length vs. Complexity
A 20-character password using only lowercase letters has more entropy than a 10-character password using all character types. Length is the single most important factor in password strength. However, combining length with a diverse character set produces the strongest possible passwords. This tool defaults to 16 characters with all character types enabled.
