β‘ WHY YOU NEED THIS
Most password generators are online. That's dangerous.
π¨ ONLINE GENERATORS CAN:
β Send your passwords across the internet
β Log everything you generate on their servers
β Be hacked and leak your data
β Track your usage patterns
β Sell your information to third parties
β¨ UNBREAKABLE IS DIFFERENT:
β 100% Offline β No internet required, ever
β Zero Network Requests β Provably verifiable in dev tools
β Cryptographically Secure β Web Crypto API, not Math.random()
β No Data Collection β Nothing logged, stored, or transmitted
β Fully Open Source β Complete transparency on GitHub
β No Trust Needed β Verify everything yourself

π¬ SECURITY DEEP DIVE
π CRYPTOGRAPHICALLY SECURE RANDOMNESS
Uses window.crypto.getRandomValues() for TRUE cryptographic randomness.
NOT using Math.random() which is predictable and unsafe for passwords.
𧬠NO MODULO BIAS
Implements rejection sampling to ensure uniform distribution. This is the
EXACT technique used by 1Password and LastPass. Eliminates mathematical
bias that could make passwords predictable.
π ENTROPY CALCULATION
Password strength measured by: Entropy = Length Γ logβ(Character Set Size)
πͺ EXAMPLE: 16-character password with all character types
β’ Character set: 94 characters (A-Z, a-z, 0-9, symbols)
β’ Entropy: ~105 bits
β’ Time to crack: TRILLIONS OF YEARS
(at 100 billion attempts/second with modern GPUs)
π OFFLINE OPERATION
Zero network requests = Zero attack surface
β’ No servers to hack
β’ No logs to leak
β’ No data to breach
β’ Generated on YOUR device
β’ Stays on YOUR device
β’ Period.
