Public Release #02 - Signup with WhatsApp

A WhatsApp authentication tool to login users without an OTP.

With over 2 billion monthly active users, there has been a rise in products built on top of WhatsApp.

Opportunity and value hypothesis

We identified an opportunity around user authentication. Time and time again our products have faced drop-offs during signup due to failed OTP deliveries.

Our hypothesis is that just like ‘Signup with Google’, ‘Signup with WhatsApp’ will become the go-to source for signups, especially in markets where a phone number is the primary method of authentication instead of email. We believe:

• It’s easy for users. Not having to remember passwords or enter OTPs manually.

• It’s better for companies. Only real users and no more drop-offs due to SMS delivery issues.

Week 1: User journey mapping

In our first week of building, we mapped out the user flows and worked on wireframes.

Week 2: Building the MVP

We used the WhatsApp Cloud APIs with Glitch as the server and the front end was built in bubble.io

What’s Next

• The initial testing showed a 100% success rate for signup but we still have to test on a reasonable scale.

• The cost of one message is PKR 3 for us compared to PKR 1 for local SMS and PKR 14 for international SMS (via Twilio). It definitely makes sense for international products but not for locals.

• We have now rolled out a waitlist on Product Hunt to gauge the demand for this product in the market.

• If you’re interested in testing out your product, you can request early access on the website here.

Stay tuned to learn about the next product we’ll be releasing soon. Thanks!
