Insecure vs Secure: Same App, Two Builds
The same mobile app on Azure, built two different ways.
What you'll learn
- Why the insecure architecture ships first — it genuinely works
- The six moments where the two designs stop behaving the same
- Why the difference only shows up when something goes wrong

Two ways to build it
Top: the app talks straight to the database. Bottom: it never does. Both compile, both demo fine — only one survives an attacker.
Frequently asked questions
- If the insecure design works, why does it matter?
- Because "works" and "survives" are different claims — the insecure design ships first and behaves identically to the secure one right up until the six moments things go wrong: a leaked key, a stolen token, an oversized permission, and so on. The difference is invisible until then.
- What's the real cost of the insecure design?
- Every fix becomes an app store release you don't control the timing of, gated by a reviewer, while the secure design keeps every fix server-side. That gap in response time is what actually separates the two builds.

These are built for a phone
Every short is drawn at full portrait height, the shape a phone already is. Installed, it opens full-bleed with no address bar across the top — and the whole library reads offline.
