Password Generator
Create cryptographically secure, fully customizable passwords instantly — 100% private, runs entirely in your browser.
About the Password Generator
This tool creates cryptographically secure random passwords directly in your browser using the Web Crypto API (crypto.getRandomValues()) — the same source of randomness used for SSL/TLS connections. Nothing is sent to a server, logged, or stored.
Is this password generator secure?
Yes. It uses a cryptographically secure pseudo-random number generator (CSPRNG) built into your browser, not Math.random(), which is predictable and unsuitable for security purposes.
How long should my password be?
For most accounts, 16 characters is a solid minimum. For highly sensitive accounts such as email or your password manager's master password, use 20-32 characters with all character types enabled.
Are my passwords stored anywhere?
No. Everything happens locally in your browser tab. Refresh the page and the password is gone — nothing is ever transmitted or saved.
About the Password Generator
Our free password generator creates strong, random passwords of any length using any combination of uppercase letters, lowercase letters, numbers, and special characters. Generated passwords are cryptographically random, ensuring they cannot be guessed or predicted. All generation happens in your browser — no passwords are ever transmitted or stored.
Weak passwords remain one of the most common causes of account compromise. "123456", "password", and simple dictionary words are cracked instantly by modern brute-force tools. A truly random 16-character password with mixed character types would take longer than the age of the universe to crack with current technology.
Password Strength Guide
- 8 characters, letters only — Weak. Can be cracked in minutes by modern computers.
- 12 characters, mixed case + numbers — Moderate. Reasonable for low-importance accounts.
- 16 characters, all character types — Strong. Recommended for most accounts including email and banking.
- 20+ characters, all character types — Very strong. Ideal for master passwords and high-value accounts.
How to Use the Password Generator
- Set password length — Use the slider to choose between 8 and 64 characters. We recommend at least 16.
- Choose character types — Toggle uppercase letters, lowercase letters, numbers, and symbols independently.
- Exclude ambiguous characters — Optionally exclude characters like 0/O and 1/l/I that are hard to distinguish when reading.
- Click Generate — A new random password appears instantly.
- Click to copy — Copy the password to your clipboard with one click.
- Generate again — Click Generate as many times as you like to get a new password each time.
Best Practices for Passwords
- Use a unique password for every account — If one site is breached, attackers cannot reuse your password elsewhere.
- Use a password manager — Tools like Bitwarden, 1Password, or KeePass store all your unique passwords securely so you only need to remember one master password.
- Enable two-factor authentication (2FA) — Even a strong password can be stolen via phishing. 2FA adds a second layer of protection.
- Never reuse passwords — Credential stuffing attacks automatically try leaked username/password combinations on other sites.
Frequently Asked Questions
Is the generated password stored anywhere?
No. Password generation uses the browser's cryptographic random number API. No passwords are sent to our servers or stored in any log.
How random are the generated passwords?
Passwords are generated using the Web Crypto API's getRandomValues() function, which provides cryptographically secure randomness — the same standard used in professional security tools.
Can I use symbols in passwords for all websites?
Most modern websites accept all printable ASCII symbols. A small number of older sites restrict special characters. If a site rejects a generated password, regenerate with only alphanumeric characters.
How long should a password be?
For most accounts, 16 characters with mixed character types provides excellent security. For master passwords on password managers, use 20+ characters.
