Password Best Practices
• Use at least 12 characters — 16+ for important accounts
• Never reuse passwords across sites
• Use a password manager to store passwords securely
• Enable two-factor authentication wherever possible
• Change passwords after any known breach
What Makes a Strong Password?
Password strength comes from entropy — the number of possible combinations. Each additional character type multiplies the search space: a 12-character password using all four character types has ~95¹² ≈ 5.4 × 10²³ possible combinations, making brute-force infeasible.
This generator uses JavaScript's Math.random() for client-side generation — your password is never sent to any server. For maximum security, use the Web Crypto API in production applications (crypto.getRandomValues()).
