✨ Building Passwordless Authentication: A Complete Guide to Email OTP Login
Say goodbye to password fatigue. Here’s how to build a secure, user-friendly OTP authentication system in under 200 lines of code.
🎯 WHAT IS OTPLY EMAIL AUTHENTICATION CLIENT CODE?
This is Email Authentication Client Code leveraging the OTPLY the central software to get the API Key and Secret and configure in this client code and make it work for the user’s application to run successfully with the modern password-less feature.
The Password Problem We All Face
Let’s be honest: passwords are a mess. Users forget them, reuse weak ones across multiple sites, and the constant “reset password” dance frustrates everyone. Meanwhile, developers struggle with secure password storage, complex validation rules, and inevitable security breaches.
What if there was a better way?
Enter Passwordless Authentication
Email-based One-Time Password (OTP) authentication is the elegant solution that’s been gaining massive traction. Think of how you log into Slack, Medium, or countless modern apps—just enter your email, receive a code, and you’re in. No passwords to remember, no complex requirements, just simple and secure.
Today, I’ll walk you through building a complete OTP authentication system from scratch. We’ll create a beautiful, production-ready login flow that you can implement in your own projects.
What We’re Building
Our authentication system will feature:
✨ Clean, modern UI with a stunning gradient design
🔒 Secure OTP generation with 10-minute expiration
📧 Email delivery through a reliable API service
🚀 Session management for authenticated users
📱 Mobile-responsive design that works everywhere
