What is a Password Generator?

A password generator creates strong, random passwords that are significantly harder to crack than passwords chosen by humans. People tend to create predictable passwords — using names, birthdays, or common words — that are vulnerable to dictionary attacks and brute-force attempts. A random password generator eliminates this bias by using cryptographically random character selection, producing passwords that are statistically secure.

Cybersecurity experts universally recommend using a unique, randomly generated password for every account. With the average person managing dozens or hundreds of online accounts, a password manager combined with a password generator is the industry-standard approach. Our tool generates passwords using JavaScript's Math.random() and lets you control length (6–64 characters), character types (uppercase, lowercase, numbers, symbols), and quantity (up to 20 at once).

How to Use the Password Generator

1. Adjust the Length slider (6–64 characters). Longer is stronger — aim for at least 16.
2. Check or uncheck character types: Uppercase, Lowercase, Numbers, and Symbols.
3. Choose how many passwords to generate (1, 5, 10, or 20).
4. 点击 Generate Passwords. Click the copy icon next to any password to copy it individually, or Copy All to copy all passwords at once.
