About Us
pass-seisei.com provides a secure and reliable password generation service.
🎯 Our Mission
As online security threats continue to grow, our mission is to provide everyone with an easy way to create strong passwords. We offer a free tool that generates secure passwords with just one click, without requiring complex settings or technical knowledge.
🔐 Our Security Technology
Browser-Based Encryption
All encryption algorithms used by pass-seisei.com run entirely in your browser. We use the Web Crypto API, a cryptographically secure random number generator built into modern browsers. Generated passwords are never sent to any server.
No Server Storage
Our service never stores or logs generated passwords or any input data on servers. All processing happens locally on your device, making it impossible for third parties to access your data. Only you know your passwords.
Cryptographically Secure Random Generation
Unlike common random number generators (like Math.random()), we use crypto.getRandomValues(). This is a Cryptographically Secure Pseudo-Random Number Generator (CSPRNG) that produces unpredictable, high-quality random numbers. This technology ensures generated passwords are statistically unbiased and extremely difficult for attackers to guess.
