Strong Password Generator

Create strong, random passwords instantly with our free online password generator. The tool uses the browser's crypto.getRandomValues() method — part of the Web Crypto API — to produce truly cryptographically secure random values. Unlike pseudo-random generators, this API draws entropy from the operating system, making the output unpredictable and suitable for security-critical applications.

You can customize your password with various options: choose a length from 4 to 128 characters, toggle uppercase letters (A-Z), lowercase letters (a-z), numbers (0-9), and special symbols (!@#$%^&*). A real-time strength indicator shows you how secure your password is, based on character diversity and length. For maximum security, we recommend at least 16 characters with all character types enabled.

All generation happens 100% in your browser — no password is ever transmitted to any server. There are no logs, no cookies, and no tracking. Your passwords remain completely private.

Best practices for password security: Use a unique password for every account. Never reuse passwords across services. Enable two-factor authentication (2FA) wherever possible. Consider using a password manager like Bitwarden, 1Password, or KeePass to store your passwords securely. Change passwords immediately if you suspect an account has been compromised.

facilita.tools also offers other security and developer tools: validate CPF numbers, validate CNPJ numbers, or generate test data with our CPF Generator.

Frequently Asked Questions

Is this password generator safe?
Yes. Passwords are generated entirely in your browser using the Web Crypto API. Nothing is sent to our servers — the same privacy model used by our CPF Validator and other tools.
What is a strong password?
A strong password has at least 12 characters, mixing uppercase letters, lowercase letters, numbers, and special symbols. Avoid personal information and never reuse passwords across services.
What is the ideal password length?
For personal accounts, at least 16 characters. For critical systems (banking, admin), 20 or more. Always enable two-factor authentication (2FA) for extra security. Our generator creates up to 128-character passwords.
