I'm building a mobile app that relies on a backend API, and I'm looking for ways to keep that API secure from unauthorized use. I already plan to implement standard email/password authentication and JWT tokens, but I'm worried about people accessing my backend directly from outside the app. I considered using an API key embedded in the app, but I know that anyone could decompile the app and find it. What are some effective techniques for protecting my backend API? Am I overthinking this, or is security a genuine concern? I'd appreciate any advice!

You're definitely right to be concerned. Implementing techniques like certificate pinning can greatly enhance security by ensuring your app only communicates with your authorized server. Also, consider tying API sessions to specific devices, using short-lived API keys that aren't hardcoded, and adding backend checks like device fingerprinting. While no app can ever be 100% secure, the goal is to deter attackers as much as possible.
These sound like practical measures! I’ll do some research into them—thanks!
Have you looked into Firebase's AppCheck? It's specifically designed to protect against abuse, and it might be worth considering for your app.
Thanks for the suggestion! I’ll check that out too.
You're welcome! Hope it helps!
Check out iOS's "App Attestation" API and Google's "Play Integrity" API. They’re designed to help prevent unauthorized access to your backend. While they have limitations, they provide useful tools to secure your app. As for being paranoid about security, it really depends on what data you're handling. If it’s sensitive, it’s worth taking precautions!
Thanks for the tips! My app is just a simple game for now, but I want to make sure I learn the right lessons for future projects. I'll look into those APIs!
No problem! Best of luck with your app!
Glad to help! It's all about making it tough for potential attackers.
