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

Frequently Asked Questions
NIST (National Institute of Standards and Technology) recommends at least 8 characters, but security experts now suggest 12–16 characters as the minimum for important accounts. For maximum security (banking, email, password managers), use 20+ characters. A 16-character random password with mixed characters would take billions of years to crack with current technology.
This tool uses JavaScript's Math.random() which is a pseudorandom number generator. It is suitable for generating passwords for personal use but is not cryptographically secure. For applications requiring true cryptographic randomness (generating encryption keys, API tokens), use crypto.getRandomValues() which accesses the operating system's secure random number generator.
Yes, if the service allows it. Symbols dramatically increase the character pool — from 62 characters (letters + numbers) to 95+ characters — exponentially increasing the number of possible combinations. Some older systems do not accept certain symbols, so if your password fails, try disabling symbols. A longer password without symbols can be just as secure as a shorter one with symbols.
Use a reputable password manager (1Password, Bitwarden, KeePass, or your browser's built-in manager). Never store passwords in plain text documents or spreadsheets. A password manager encrypts your vault and can auto-fill passwords, eliminating the need to remember or type them. Enable two-factor authentication (2FA) on your password manager for an additional security layer.
