Secure Random Password Generator
This tool creates cryptographically secure random passwords to protect your online accounts. It generates strong passwords using a combination of uppercase/lowercase letters, numbers, and special characters, ensuring maximum security against brute-force attacks.
How to Use
1. Click 'Generate Password' to create a new 16-character password
2. Use 'Copy Password' to save to clipboard
3. Download barcode for physical storage
4. Always store passwords securely
5. Generate new passwords for each account
Password Generation Formula
Password = [A-Z] + [a-z] + [0-9] + [special chars] × 16 characters
Using cryptographically secure window.crypto.getRandomValues() API
Character pool: 94 possible characters (26+26+10+32)
What makes this password generator secure?
Our tool uses window.crypto.getRandomValues(), a cryptographically secure random number generator built into modern browsers. This ensures true randomness rather than pseudo-randomness, making the passwords virtually impossible to predict or brute-force.
Can I customize the password length?
The current version generates fixed 16-character passwords containing at least one character from each category (uppercase, lowercase, number, special). This provides optimal security while maintaining memorability. Future versions may include length customization.
Why download a barcode?
The barcode download option provides a secure way to physically store passwords. It eliminates digital storage risks while maintaining readability. The barcode uses Code128 format which can be scanned by most barcode readers.
How does this differ from other password generators?
Our tool combines client-side generation (no server involvement) with military-grade randomness and barcode download capability. This ensures your passwords never leave your device and remain completely private.
