🔐 scan-for-secrets: The Free Tool That Catches Leaked Passwords Before Hackers Do

Have you ever accidentally pushed an API key or database password to a public repository?

You're not alone — and the consequences can be devastating.

• Leaked credentials are one of the top causes of data breaches
• A single exposed token can compromise an entire infrastructure
• Once it's in git history, it's incredibly hard to fully remove

Simon Willison highlights scan-for-secrets, an open-source tool that scans your entire codebase for secrets that shouldn't be there — API keys, tokens, passwords, private keys, and more.

🎯 Why it matters:

• Free and open source — install in minutes
• Detects multiple secret patterns (AWS keys, private keys, tokens)
• Works on existing repos and integrates into CI/CD pipelines
• Catches mistakes before they reach production
• Perfect for solo developers and large teams alike

Think of it as a security guard checking every bag before it leaves the building. If something sensitive is about to slip out, you'll know immediately.

In an era where data breaches make headlines daily, tools like this aren't optional — they're essential.
