Password Generator
Generate secure, random passwords with real-time strength analysis.
About Password Generator
Create cryptographically secure passwords instantly using your browser's Web Crypto API. Customize length (8-128 characters), include uppercase letters, lowercase letters, numbers, and special symbols. Get real-time password strength analysis and entropy calculation. Your passwords never leave your device.
Unlike many online password generators, ours runs 100% in your browser using the Web Crypto API. Your passwords are never transmitted to any server — we literally cannot see them. This makes it one of the safest online password generators available.
How to Use Password Generator
- 1Set your desired password length using the slider (8–64 characters). We recommend at least 16 characters.
- 2Select which character types to include: uppercase letters (A–Z), lowercase letters (a–z), numbers (0–9), and symbols (!@#$%...).
- 3Click 'Generate' to create a cryptographically secure random password.
- 4Check the strength meter — aim for 'Strong' (green) before using a password.
- 5Click 'Copy' to copy the password, then paste it into your password manager.
Key Features
Use Cases for Password Generator
Online Account Security
Generate unique, complex passwords for every online account. Using different passwords for each site means a breach on one site doesn't compromise your other accounts.
Password Manager Setup
Create ultra-strong master passwords for password managers like 1Password, Bitwarden, or LastPass. A 24-character mixed password is effectively impossible to brute-force with current technology.
API Keys & Tokens
Generate secure random strings for API keys, session tokens, encryption keys, and database passwords. Use 32+ characters with all character types enabled for maximum entropy.
Wi-Fi Passwords
Create a strong Wi-Fi password that's secure without being impossible to share. A 16-character password with letters and numbers is both strong and relatively easy to type on a phone.
Never reuse passwords across sites. Use our generator to create a unique 20+ character password for every account, and store them in a free password manager like Bitwarden. The generator creates passwords using your device's cryptographic random number generator — they are mathematically unpredictable.
Frequently Asked Questions
Is this password generator safe to use?
Yes. All passwords are generated entirely in your browser using the Web Crypto API — nothing is sent to our servers. Your passwords are 100% private.
How long should my password be?
Security experts recommend at least 16 characters for important accounts. Our generator defaults to 20 characters, which provides over 100 bits of entropy — effectively uncrackable.
Should I use special characters in passwords?
Yes. Including symbols like !@#$%^&* dramatically increases password complexity. A 16-character password with all character types would take billions of years to brute-force.
