Firebase can be very secure when properly configured. The platform itself has strong security foundations, but your implementation determines actual security.
Firebase's security depends on two factors:
2. **Your Configuration**: Most security issues come from misconfiguration, not platform vulnerabilities. You need to: - Configure database security rules - Keep secrets out of frontend code - Set up proper authentication - Add security headers
Bottom line: Firebase provides the tools for secure apps, but you must use them correctly. Scan your app to verify your configuration.

“Vibe coding your way to a production codebase is clearly risky. Most of the work we do as software engineers involves evolving existing systems, where the quality and understandability of the underlying code is crucial.”
“The problem with AI-generated code isn't that it doesn't work - it's that it works just well enough to ship, but contains subtle security flaws that are hard to spot.”
