Password Less Login

Password Less Login is a passwordless and OTP-based login system for WordPress.
Every user — both existing and new — must verify their identity using a One-Time Password (OTP) sent to their email before being logged in.

This ensures that no one can access an account without confirming ownership of the email address, providing a secure, passwordless authentication process.

How It Works

1. The user enters their email address.
2. The plugin sends a 6-digit OTP to that email.
3. The user enters the OTP:
   • If the email exists → the user is securely logged in.
   • If the email is new → the user provides a username, verifies the OTP, and a new account is created automatically.
4. The OTP is valid for 10 minutes and expires after use.

Note: The plugin never logs in users without OTP verification.

Key Features

• OTP-Based Authentication for All Users – Both existing and new users must verify the OTP before login.
• Passwordless Login – Securely log in using only your email and OTP.
• Auto User Registration – New users can register instantly after OTP verification.
• Temporary OTP (10 Minutes) – Each OTP expires after 10 minutes and can only be used once.
• Rate Limiting – Prevents brute-force or spam OTP requests (maximum 5 per 15 minutes per email).
• Nonce Verification – Protects REST API endpoints from unauthorized access.
• Secure Email Handling – Emails are hashed when stored in transients to protect user data.
• Streamlined User Experience – Clean, minimal login flow with conditional fields for existing vs. new users.

Why Choose Password Less Login?

   • If your account exists, you’ll be logged in.
   • If not, you’ll be prompted to provide a username before registration and login.
5. You’ll be redirected to your dashboard after successful verification.
