Users can authenticate using username/password:
// In your componentconst{ login, loading, error }=useAuth();consthandleLogin=async()=>{awaitlogin(username,password);};Direct authentication with license keys:
const{ licenseAuth }=useAuth();consthandleLicenseLogin=async()=>{awaitlicenseAuth(licenseKey);};const{ enable2FA }=useAuth();// This returns a QR code URL for the user to scanconstresult=awaitenable2FA();if(result.success){// Show QR code: result.qr}When 2FA is enabled, the login flow automatically detects and redirects to 2FA verification:
const{ loginWith2FA }=useAuth();consthandleVerify2FA=async(code: string)=>{awaitloginWith2FA(username,password,code);};const{ disable2FA }=useAuth();consthandleDisable2FA=async()=>{awaitdisable2FA();};const{ register }=useAuth();consthandleRegister=async()=>{awaitregister(username,password,licenseKey);};Users can upgrade their accounts with additional license keys:
const{ upgrade }=useAuth();consthandleUpgrade=async()=>{constresult=awaitupgrade(username,licenseKey);if(result.success){// Show success message}else{// Show error: result.message}};Access current user information through the context:
const{ user, isLoggedIn }=useAuth();// User object contains:console.log({username: user?.username,email: user?.email,ip: user?.ip,hwid: user?.hwid,expires: user?.expires,subscriptions: user?.subscriptions,createdate: user?.createdate,lastlogin: user?.lastlogin});Display app statistics:
const{ keyauth }=useAuth();// Access app dataconstappData=keyauth?.app_data;console.log({numUsers: appData?.numUsers,onlineUsers: appData?.onlineUsers,numKeys: appData?.numKeys,version: appData?.app_ver,customerPanel: appData?.customer_panel});const{ logout, keyauth }=useAuth();// Check if session is validconstisValid=awaitkeyauth?.check();// Logout userlogout();const{ keyauth }=useAuth();constisBlacklisted=awaitkeyauth?.checkblacklist();if(isBlacklisted){// Handle blacklisted user}const{ keyauth }=useAuth();// Ban current user (must be logged in)awaitkeyauth?.ban();Send logs to KeyAuth dashboard:

bun startbun run type-checkbun run lintThe application uses Tailwind CSS with custom KeyAuth design tokens. Main colors:
/* Custom background colors */
.bg-custom-back { /* Dark background */ }
.bg-custom-back-1 { /* Darker background */ }
/* Custom hover effects */
.hover:bg-blue-700 { /* Button hovers */ }The AuthContext provides all authentication state and methods. Wrap your app with AuthProvider:
import{AuthProvider}from'@/contexts/AuthContext';exportdefaultfunctionRootLayout({
children,}: {children: React.ReactNode;}){return(<htmllang="en"><body><AuthProvider>{children}</AuthProvider></body></html>);}This is common amongst all authentication systems. Program obfuscation causes false positives in virus scanners, and with the scale of KeyAuth this is perceived as a malicious domain. So, keyauth.com and keyauth.win have been blocked by many internet providers. For dashboard, reseller panel, customer panel, use keyauth.cc.
For API, keyauth.cc will not work because it's purposefully blocked there so keyauth.cc doesn't get blocked also. You should create your own domain and follow this tutorial video: https://www.youtube.com/watch?v=a2SROFJ0eYc
