Why Math.random() is Insecure

Standard JavaScript Math.random() uses linear pseudo-random algorithms (XorShift128+) that can be mathematically reversed after observing a few outputs.

AZBrand utilizes window.crypto.getRandomValues(), which pulls high-entropy noise directly from hardware interrupt timing and thermal noise sources, providing true cryptographic nonces.

Security Best Practices

Password Management & MFA

A secure password is only effective if it is never reused across services. Store all credentials in an encrypted password manager and enforce Multi-Factor Authentication (TOTP / FIDO2 Hardware Keys) across all accounts.

Rotate any credentials immediately if a third-party service notifies you of a data breach.
