Stop exposing your API keys to the cloud.

The Intuition

Every time you paste an API key, you’re taking a risk. Cloud-based password managers are convenient, but they are also massive targets for hackers.

Lock N' Key takes a radical approach: Zero Trust Networking.

We store your data exclusively on your machine, encrypted with AES-256-GCM. No "sync servers", no "master keys" on our end, and absolutely no outgoing internet requests from the core vault. It's the digital equivalent of a physical safe in your home office.

Lead Developer & Security Enthusiast

"I asked myself: Can I manage my keys in a way that's actually developer-friendly? I was tired of using notepad files, which led me to create Lock N' Key.

This is the first version (v1.0), and I have many future enhancements planned. I personally invite fellow developers to try it out, use it, and share any ideas or feedback. If you encounter bugs, please report them—your input is invaluable for improving the app."
