Password Generator - Free Online Tool | Convixpro
Generate secure, random passwords.
⚡ Fast, Private & Free Browser Utility
The Password Generator uses the browser's native Web Crypto API (window.crypto.getRandomValues) to generate and evaluate high-entropy, mathematically unpredictable passwords. Protect your accounts against brute-force and dictionary attacks with zero server transmission.
How to Use Password Generator Step-by-Step
Follow these straightforward steps to complete your task quickly and securely:
- Configure Password Length: Choose your desired length between 8 and 128 characters (we recommend 16+ for sensitive accounts).
- Set Character Rules: Toggle uppercase letters, lowercase letters, numbers, and special symbols (@, #, $, %, etc.).
- Generate Instant Entropy: Cryptographically secure hardware randomness generates unique passwords in sub-milliseconds.
- Copy Safely: Click to copy to your clipboard. Your password exists only in local memory and is never saved or logged.
Key Advantages & Guarantees
Hardware-Grade Cryptographic Entropy
Powered by the browser's CSPRNG (Cryptographically Secure Pseudo-Random Number Generator).
Zero Cloud Transmission
Your passwords never touch any server or cloud API; they are generated 100% in local memory.
No Storage or Telemetry
We do not log, track, or retain any generated credentials.
Crack-Time & Entropy Estimation
Real-time bit-entropy metrics and brute-force crack time estimates help ensure bulletproof security.

Frequently Asked Questions
Are generated passwords saved on Convixpro servers?
Never. Passwords are created entirely inside your browser using the local Web Crypto API. Neither Convixpro nor any third party ever receives or stores your password.
What makes a password cryptographically secure?
A secure password has high entropy (length of 16+ characters, diverse character sets, and unpredictable randomness from a CSPRNG) making brute-force cracking mathematically infeasible.
Can I generate passwords while disconnected from the internet?
Yes. Once this page is loaded, the generator operates completely offline without needing an active internet connection.
Should I reuse the same password for multiple services?
No. You should always use a unique password for every account so that a data breach on one platform doesn't compromise your other accounts.
