Integrate Login with WhatsApp

Enhance personalisation for brand marketing

Do you know how many active users WhatsApp has?

It’s over 2 billion worldwide.

With this high number, doesn’t it make a lot of sense for businesses to interact with their customers via WhatsApp as it can help them reach their target audiences’ inboxes and offer their products easily?

Currently, WhatsApp is the most used conversational application globally and accounts for more than 100 billion messages sent daily to users. With such high numbers, today we’ll see another use of WhatsApp, using it for Logging into a platform.

What is Login with WhatsApp

"Login with WhatsApp" is an authentication feature that allows users to access websites or apps using their WhatsApp credentials. 

Simply, instead of creating another username and password combination, users can log in seamlessly by clicking a button that authenticates them through their WhatsApp account. 

Think of it like while trying to log into a platform, you use ‘Login with Google Account’, similar is Login with WhatsApp, the only difference is the authentication now happens via your WhatsApp account

Why is Login with WhatsApp required?

But why in the first place would you want a third-party service, WhatsApp login to be a part of your signup process? 

Before we answer the above question, we want to ask you:

What benefit do you have by optimising your platform regularly? Why doesn’t a single iteration work forever?

As times change, user expectations are changing. The user doesn’t have time to remember 100s of usernames and passwords. This is where the user expects some easier yet secure way to in exchange for the traditional way of entering details and passwords.

This is where Login with WhatsApp acts as a saviour for the D2C brand. Let’s see its benefits:

Simplifies the User Experience

Users are often overwhelmed with remembering login credentials, and "forget password" is a common problem. WhatsApp Login eliminates this process by providing a one-click login solution.

Enhances Security

With end-to-end encryption being the base of WhatsApp conversations, it acts as a trusted process and makes it a secure way to authenticate users. This reduces the risk of data breaches and unauthorised access.

Boost User Acquisition and Retention

By providing a convenient and familiar login method, businesses especially D2C brands can attract more users and keep them engaged. The best part is with users’ WhatsApp details, you can also engage with them on marketing materials like offers, product launches, clearance sales, etc.

Where can Login with WhatsApp be used

The versatility of Login with WhatsApp makes it applicable in various domains. It’s like wherever there is a sign-in option, logging in with WhatsApp can work there. 

But, the most common platforms where Login with WhatsApp is used as a feature to simplify user experience are:

  1. e-Commerce platforms
  2. Social media networks
  3. Fitness platforms
  4. Healthcare apps
  5. Or any app or website that requires user authentication

Difference between SMS OTP Login vs. WhatsApp Login

While SMS OTP (One-Time Password) login has been in use for years, it has its drawbacks.

With factors such as poor connection, and delay on the server side to send out messages, OTPs can be delayed or lost in such conditions. Additionally, users may need to switch between apps to retrieve OTPs, causing a bad user experience.

On the other hand, WhatsApp Login offers a smoother experience. It's faster and more reliable since it operates within the WhatsApp platform only. Moreover, users don't need to leave your app or website to authenticate, reducing dropout rates. 

WhatsApp offers two-factor authentication, an Added Layer of Security

The OTP received on WhatsApp acts as a secondary step in making sure that the mobile number associated and the user trying to log in are the same and the rightful owner of the account. 

While it provides a smooth sign-in or sign-up process, you can make sure that sufficient security checks have been done while onboarding the user as well.

Register as a WhatsApp Business

To use Login with WhatsApp for authentication on your platform, you need to register your platform as a WhatsApp Business account first. This involves creating a WhatsApp Business Account and obtaining the necessary API credentials.

Integrate WhatsApp API

Once you’re done with setting up the WhatsApp business account, you then have to integrate the WhatsApp Business API into your platform’s backend. This requires your tech team’s bandwidth to ensure a seamless integration.

Implement User Authentication

Develop the authentication flow for your app. This includes providing users with the option to log in with WhatsApp - Add the “Login With WhatsApp” button to your app’s login page.

This button will ensure that redirection of the user to WhatsApp happens via this button to handle authentication requests, and securely manage user data.

Testing and Compliance

Thoroughly test your "Login with WhatsApp" feature to ensure it functions correctly. Now you can define your own sign-in/sign-up flow.
