Password Generator
Generate secure, cryptographically random passwords with customizable options. Your passwords never leave your browser.
About This Password Generator
This password generator uses the Web Crypto API (crypto.getRandomValues()) to generate cryptographically secure random passwords. Unlike many online generators, this tool runs entirely in your browser — your passwords are never transmitted over the network or stored anywhere.
How to Create a Strong Password
Security experts recommend passwords that are:
- At least 16 characters long — longer passwords are exponentially harder to crack
- Mix of character types — uppercase, lowercase, numbers, and symbols
- Randomly generated — avoid dictionary words, names, dates, or patterns
- Unique for each account — never reuse passwords across sites
Password Strength Explained
The strength indicator estimates how resistant your password is to brute-force attacks:
- Weak (Red) — Can be cracked quickly, add more length and character types
- Moderate (Yellow) — Reasonable security for low-value accounts
- Strong (Green) — Suitable for important accounts when combined with 2FA
Why Use a Password Generator?
Humans are terrible at creating random passwords. We tend to use predictable patterns, personal information, and common substitutions (like @ for a) that attackers know to check. A true random generator eliminates these weaknesses.
