What's the best way to do authentication in modern applications

# Summary Modern authentication in frontend applications involves trade-offs between different token storage approaches, each with distinct security implications. The article examines common methods like localStorage, memory storage, and httpOnly cookies, explaining how each addresses vulnerabilities like XSS and CSRF attacks, while also exploring JWT-based stateless authentication versus session-based approaches. The key insight is that there is no single "best" solution—the choice depends on specific security concerns and use cases, requiring developers to understand the vulnerabilities each method protects against.
