Interested in integrating with Key-Rex? Here’s a clear guide with the steps to integrate Key-Rex Bitcoin Lightning Authentication into your website. 1. Get a Lightning Wallet If you don’t have one yet, download a compatible Lightning wallet app. This is what you’ll use to create your Key-Rex account and what your visitors will use to sign in. 2. Create Your Key-Rex Account Go to keyrex.co and sign in with your Lightning wallet. It’s fast, passwordless, and creates your account instantly. 3. Enter Your Domain Tell Key-Rex the domain (website address) where you’ll be using the authentication. 4. Accept the Disclaimer and Get Your Site ID Review the quick disclaimer, accept it, and you’ll receive your unique site ID plus the integration code right away (available in your dashboard). 5. Add the Frontend Code Embed the Key-Rex login button on your website by adding these two lines to your HTML - check website for code (Replace `YOUR_SITE_ID` with the one from your dashboard.) 6. Set Up Backend Callback Handling Your backend (or a simple serverless function on Vercel, AWS, etc.) needs to receive the authentication callback. It gets a secure cryptographic proof like `{ "xpub": "xpub_..." }`. Use this to create a user session and redirect the user after login. Full working examples for different languages and frameworks are provided in your Key-Rex dashboard. 7. Test and Go Live Test the login flow on your site. Users will see a simple “Sign in with Lightning” button, connect their wallet, and log in instantly with no passwords or emails collected. That’s it. Head over to

Just like the zipper quietly revolutionized clothing by making "secure + fast + personal" the default (and now we can't imagine life without it—seriously, try putting on button-fly jeans every day and report back), Bitcoin Lightning Auth is doing the same for digital identity. It takes something you already trust (your Lightning wallet) and turns it into the effortless, sovereign "zipper" for logging in everywhere.

Every Lightning wallet already holds the keys to seamless, secure logins. Key-Rex simply makes that power usable across the web—private by design, with zero credential storage. For developers: clean integration. For users: true self-custody at login. Strengthen your site’s security the Bitcoin way. ⚡ #WebDev #BitcoinAuthentication

Instead of user credential notifications leaked at 3am, your users just zap a Lightning invoice and they’re in. No more “let me reset it real quick” support tickets. The dev crowd is about to be in the Key-Rex t-shirts, chugging coffee, and coding it live. Who’s integrating next? 👇 #Bitcoin #Lightning #KeyRex #NoMorePasswords #WebDev

The time it takes to hack your Bitcoin keys….practically infinite ♾️♾️. Give your users a way to sign-in securely without needing to worry about the length of their passwords. 😮‍💨Key-Rex Bitcoin Lightning Auth🫡

10 seconds. All it takes signing in to any website with Key-Rex.

Think your login is secure? Well it’s not compared to BTC Lightning wallet via Key-Rex.🤣 It’s pure Bitcoin cryptography. A supercomputer trying to hack your account? It would need to make 1.1579 × 10^77 tries to brute-force your private key. To put that in perspective: - There are ~10^80 atoms in the observable universe. - Even if every supercomputer on Earth worked together at maximum speed… It would still take billions of billions of years longer than the age of the universe to guess your key. Your Lightning wallet login is literally uncrackable by any classical computer. Period. 😃

Quick thought: Your private keys are like the real key to your house—the most powerful thing you own digitally. You guard it, it’s yours forever. But we still treat logins like those cheap paper hotel key cards: - New one every time you “stay” - Hand it over without thinking - Easy to lose, copy, or reuse - No real control or ownership Lightning auth changes that. One cryptographic signature = instant proof it’s you. Private, secure, and truly yours. The old password system feels ancient now. Time to upgrade. #Bitcoin #LightningNetwork
