The Web Crypto API provides a secure method for generating UUID v4 identifiers directly in browsers. Standard Math.random() is cryptographically insecure, as its underlying pseudo-random state can be reverse-engineered by attackers to predict future IDs, compromising session tokens and API keys.
Client-side crypto is mature; no excuse for insecure randoms. Using the browser's native crypto API prevents predictable IDs and major security vulnerabilities.
