Password Generator
Generate strong, random passwords with customizable length and character options. Uses cryptographically secure randomness.Updated 2026-03-16
Why Use a Password Generator?
Weak passwords are the #1 cause of security breaches. Our password generator creates truly random passwords using your browser's built-in cryptographic random number generator (crypto.getRandomValues), ensuring maximum unpredictability.
What makes a strong password:
- Length: At least 12 characters; 16+ is recommended for critical accounts.
- Complexity: Mix of uppercase, lowercase, numbers, and symbols.
- Randomness: No dictionary words, names, dates, or patterns.
- Uniqueness: Never reuse the same password across different accounts.
Password strength by length:
- 8 characters: Minimum acceptable — can be cracked in hours to days.
- 12 characters: Good — would take years to brute-force.
- 16+ characters: Excellent — virtually impossible to crack with current technology.
- 20+ characters: Maximum security — recommended for master passwords.
How to Generate a Strong Password
- Set your desired password length using the slider (8-128 characters).
- Select which character types to include: uppercase, lowercase, numbers, symbols.
- Click "Generate Password" to create a cryptographically random password.
- Click the password or "Copy" button to copy it to your clipboard.
- Paste it into your password manager or account registration form.
💡 Tip: Your passwords are generated entirely in your browser. Nothing is sent to any server — your passwords never leave your device.
Frequently Asked Questions
Is this password generator secure?
Yes. Passwords are generated entirely in your browser using the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers. No passwords are sent to or stored on any server.
How long should my password be?
We recommend at least 16 characters for most accounts. For critical accounts (banking, email, password manager), use 20+ characters. The longer the password, the exponentially harder it is to crack.
Should I include all character types?
Yes, using all character types (uppercase, lowercase, numbers, and symbols) maximizes the number of possible combinations, making your password much harder to crack. Some sites may restrict certain symbols — adjust accordingly.
How do I remember complex passwords?
Use a password manager like Bitwarden, 1Password, or KeePass. They securely store all your passwords so you only need to remember one master password. Never write passwords on sticky notes or store them in plain text files.
Can someone hack a random password?
A truly random 16+ character password with mixed character types is virtually impossible to crack by brute force with current technology. The main risks are phishing, keyloggers, or data breaches — not password cracking. Always enable two-factor authentication for additional security.
