Why WhatsApp Login beats SMS and email
💬

Your users already live on WhatsApp

No more ignored emails or slow SMS. Users see the OTP where they chat every day.

💸

Cheaper and more predictable than SMS

Stop paying per-country SMS rates. One integration, global coverage via WhatsApp.

📈

Fewer logins, more conversions

Passwordless flows reduce friction at signup, checkout, and login — especially on mobile.

How LoginWA works
Three simple steps to add WhatsApp login.
1

Step 1 – Create an app

Sign up, create an app in the dashboard, and get your API keys.

2

Step 2 – Send messages and OTP

Call /api/auth/start with your user’s phone number. We pick the best WhatsApp number from the pool and send the code.

3

Step 3 – Verify and log the user in

Call /api/auth/verify. If the code matches, you get a verified phone identity you can trust.

Works with any stack — PHP, Node, Laravel, Next.js, Flutter, and more.
Built for speed, reliability, and scale

Fast messaging over WhatsApp

Optimized for fast delivery in most regions, with automatic retries if sending fails.

🔄

Shared number pool with smart rotation

Multiple WhatsApp sessions balanced automatically to reduce blocking risk.

🛡️

Cooldown-aware and failover ready

If one number is unhealthy, traffic is routed to another number in the pool.

FAQ

What exactly does LoginWA do?

LoginWA provides a WhatsApp-based authentication API so you can send messages, OTP codes, and automate WhatsApp workflows without passwords, SMS, or email.

Do you use the official WhatsApp Business API?

We manage our own pool of WhatsApp sessions and optimize delivery and rotation on our side, so you don’t have to worry about telco or messaging setup.

Can I use LoginWA with my existing stack?

Yes. If you can make HTTP requests, you can use LoginWA. We provide SDKs and examples for popular frameworks.

How do you charge for usage and how do I pay?

Each message or verification counts against your monthly quota. Pricing is in USD; Indonesian payers can also pay via QRIS, which activates instantly. Need more? Upgrade your plan or buy extra packs.

Is my users’ data secure?

We only store what we need to verify login — primarily phone numbers and OTP metadata. OTP codes are hashed and expire automatically.

Can I try it without a credit card?

Yes. The Free plan gives you a starter quota every month for testing and small projects.
