Developers: we want you building with Key-Rex. Integrate it. Test it. Try to break it. Tell us what needs to be better. If you’re building a product and want to rethink how your users authenticate, come build with us.

The internet made a strange assumption very early on: To prove you should have access to something, you should first tell a company who you are. Your name. Your email. Your phone number. A password tied to all of it. But identity and authorization are two different things. A service may need to know that you’re authorized to access an account. It doesn’t always need to know who you are. That distinction matters. The future of authentication should require less identity, not more of it.

Adding Lightning auth no longer means running your own LNURL infrastructure. Key-Rex gives you a working integration in minutes: two lines on the frontend + one backend callback. Users approve in the wallet they already have. You receive cryptographic proof. Nothing else. keyrex.co

Devs, are you working on a project and looking for more secure authentication or a different approach to user login? Key-Rex offers passwordless authentication using Lightning, giving users a simple sign-in experience without relying on traditional passwords. If you’re building something and want to try a different approach to auth, we would love to hear what you’re working on.
