Vibe-Coding 101: How to Secure Your Applications (Part 1)

AI generates a beautiful, functional piece of code and it works on the first try. But if you don't care about the security of your application, then you're easy prey for hackers. Here is how to stop "vibe-coding" security holes into your apps.

1. Never, Ever Paste Your Secrets

This is the golden rule of modern development, yet it’s the most common mistake. When you paste your API keys, database passwords, or private tokens into an AI chat, you are potentially leaking them.

• The Risk: Many AI models use your input data for training. If you feed them your "secrets," those strings could theoretically surface elsewhere or be stored in logs you don't control.
• The Solution: Use .env files (environment variables). When you share code with an AI, replace the actual key with a placeholder (e.g., `process.env.STRIPESECRETKEY`). Explicitly tell the AI: "Use this identifier name; do not ask for the actual value."

2. Don't Trust "AI-Built" Authentication

AI models are designed to be helpful and confident and they are therefore sometimes dangerous. If you ask an AI to "write a login system," it will give you a beautiful set of forms and some logic that looks perfect.
