Free Online Password Generator

Generate cryptographically secure passwords with custom length and character sets. Includes strength meter and one-click copy.

Why Use a Password Generator?

Humans are predictable when creating passwords, often using common words, birthdays, or simple patterns. A password generator creates truly random passwords using cryptographic randomness (crypto.getRandomValues), making them virtually impossible to guess.

What Makes a Strong Password?

A strong password should be at least 12-16 characters long and include uppercase letters, lowercase letters, numbers, and special symbols. A 16-character password with all four character types would take billions of years to crack.

Password Security Best Practices

Use a unique password for every account. Store passwords in a reputable password manager. Enable two-factor authentication wherever possible. Change passwords immediately if you suspect a breach.

Frequently Asked Questions

How long should my password be?
At minimum 12 characters, but 16 or more is recommended. For high-security accounts, consider 20+ characters.
Is this generator secure?
Yes. It uses the Web Crypto API (crypto.getRandomValues) for cryptographically secure random numbers. The password is generated entirely in your browser.
Should I include symbols in my password?
Yes, using all four character types maximizes password strength. Some sites restrict certain symbols, so use as many character types as allowed.
How often should I change my passwords?
Current guidance recommends changing passwords only when there is evidence of a breach. Using unique, strong passwords with two-factor authentication is more effective.
Can I remember a generated password?
Random passwords are not meant to be memorized. Use a password manager to securely store all your passwords.
