Frequently Asked Questions
How secure is this password generator?
Our generator uses the Web Crypto API's cryptographically secure random number generation (CSPRNG), the same standard used by banks and government agencies. All passwords are generated entirely in your browser using industry-standard cryptographic methods.
Are my passwords stored anywhere?
No. All password generation happens locally in your browser using JavaScript and the Web Crypto API. We have no access to your passwords - they are never transmitted to our servers or stored anywhere.
What makes a password strong?
Strong passwords combine length (12+ characters), complexity (mixed character types), and uniqueness. Our generator creates passwords that would take millions of years to crack using current technology.
Is this password generator free?
Yes, our basic password generator is completely free with no limits. Premium features including bulk generation and custom templates are available for users who need additional functionality.
Can I use this for business accounts?
Yes. Our generator uses the same cryptographic standards (Web Crypto API) as those used by financial institutions and government agencies. Suitable for both personal and business use.
How often should I change my passwords?
For most accounts, change passwords every 90 days or immediately after any security breach. Use unique passwords for each account to prevent domino-effect compromises.

How Our Password Generator Works
Our password generator uses the Web Crypto API's getRandomValues() function to create truly random passwords. This is the same cryptographic standard used by major browsers and security applications.
Technical Process:
- Your browser generates cryptographically secure random numbers
- These numbers are mapped to your selected character sets
- Password is assembled with your specified length and complexity
- No data is transmitted or stored on our servers
Password Security Best Practices for 2025
Creating strong passwords is just the beginning. Here are essential practices to protect your accounts:
Password Guidelines:
- Use at least 12-16 characters (longer is better)
- Include uppercase, lowercase, numbers, and symbols
- Never reuse passwords across multiple accounts
- Use a password manager to store passwords securely
- Enable two-factor authentication (2FA) when available
- Change passwords immediately after a data breach
