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 that are easily guessed or cracked. A password generator creates truly random passwords using cryptographic randomness (crypto.getRandomValues), making them virtually impossible to guess through brute force or dictionary attacks.
What Makes a Strong Password?
A strong password should be at least 12-16 characters long and include a mix of uppercase letters, lowercase letters, numbers, and special symbols. The more character types and the longer the password, the exponentially harder it becomes to crack. A 16-character password with all four character types would take billions of years to crack with current technology.
Password Security Best Practices
Use a unique password for every account. Never reuse passwords across services. Store your passwords in a reputable password manager rather than writing them down or saving them in plain text. 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. Longer passwords are exponentially harder to crack. For high-security accounts like banking, consider using 20+ characters.
Is this generator secure?
Yes. It uses the Web Crypto API (crypto.getRandomValues) which provides cryptographically secure random numbers. The password is generated entirely in your browser and is never sent to any server.
Should I include symbols in my password?
Yes, using all four character types (uppercase, lowercase, numbers, symbols) maximizes password strength. Some sites restrict certain symbols, in which case use as many character types as allowed.
How often should I change my passwords?
Current security guidance recommends changing passwords only when there is evidence of a breach, rather than on a fixed schedule. Using unique, strong passwords with two-factor authentication is more effective than frequent changes.
Can I remember a generated password?
Random passwords are not meant to be memorized. Use a password manager to securely store all your passwords. You only need to remember one strong master password for the password manager itself.
