Your Django REST Framework API works perfectly after login, but users suddenly receive 401 Unauthorized errors while actively using the application. In most cases, JWT authentication isn't broken—the access token has simply expired without a proper refresh strategy.
ChatGPT can scaffold RBAC middleware fast, but generic prompts produce generic code — and in access control, generic means gaps. Here's how to prompt your way to a production-ready implementation that won't leak permissions.
SSO-enabled teams often never see invitation emails, and your app silently drops them with no error. Here's how to diagnose the exact failure points and build an invitation flow that actually works for enterprise accounts.
Team account creation is where SaaS onboarding flows quietly fall apart. Invite emails get lost, roles default wrong, and new members land in broken states. Here's how to find and fix every failure point before it kills activation.
Supabase Auth is fast to ship but ties you to their platform. Lucia gives you full control but demands you write more plumbing yourself. Here's how each actually performs on DX, flexibility, and real-world lock-in risk.
WebSockets skip the browser's same-origin policy for connections — and attackers exploit that gap to send commands or steal data through a victim's live socket. Here's how the attack works and exactly how to stop it.
Your HMAC signature check looks correct, but if it uses a plain equality operator, an attacker can measure response times to forge tokens byte by byte. Here's how timing attacks work and how to fix them in every major language.
RBAC looks solid on paper, but subtle misconfigurations regularly leave admin routes, API endpoints, and sensitive settings open to users who should never see them. Here's how to find and fix the gaps before an attacker does.
IDOR vulnerabilities let attackers swap an ID in a URL and access someone else's data. They're easy to miss in code review and devastatingly simple to exploit. Here's how to find them, fix them, and keep them out of production.
Storing JWTs in localStorage feels convenient until an XSS vulnerability exposes every token on your site. Here's how to migrate your authentication to HttpOnly cookies — and why it matters more than you think.
Stripe subscription state drift happens when your database and Stripe diverge without any error — and users suddenly lose access to features they paid for. Here's how to find it, fix it, and stop it recurring.
ChatGPT can scaffold OAuth 2.0 flows fast, but it often skips PKCE, exposes tokens in URLs, or mishandles refresh logic. Here's how to prompt it correctly and catch every security gap before it ships.
