Add WhatsApp Login to your app in minutes.
LoginWA lets you send OTP over WhatsApp, verify users, and go passwordless without SMS fees or telco contracts.
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.
Step 1 – Create an app
Sign up, create an app in the dashboard, and get your API keys.
Step 2 – Send OTP over WhatsApp
Call /api/auth/start with your user’s phone number. We pick the best WhatsApp number from the pool and send the code.
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.
Fast OTP 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.

What exactly does LoginWA do?
LoginWA provides a WhatsApp-based authentication API so you can send OTP codes and log users in without passwords, SMS, or email.
Do you use 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?
Each verification attempt counts against your monthly quota. If you need more, you can 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 100 verifications per month for testing and small projects.
