With over 1.5 billion monthly users in 180 countries, WhatsApp is the world’s most popular messaging app. Today, companies use WhatsApp Business API to answer questions, send delivery updates, provide purchase receipts, and send boarding passes. But what about enabling more secure interactions, like making a payment or sharing healthcare information?

- STEP 1:
A user opts in to use voice authentication. - STEP 2:
The user is prompted to speak a short passphrase 3 times. - STEP 3:
The biometric system merges voice samples to create a voice print. The user is now enrolled. - STEP 4:
Next time authentication is required, the user simply taps the mic in WhatsApp, speaks their passphrase and hits send. - STEP 5:
Behind the scenes, voice biometrics with liveness detection ensure that the person speaking matches the enrolled user, and that the voice is not a spoof.
Authentication takes just 1-2 seconds!
Easy Two Factor Authentication in WhatsApp
Payment interfaces require Strong Customer Authentication, aka “SCA,” a regulatory requirement of PSD2 in Europe, which will likely be adopted globally. SCA requires two or more independent security factors. The device is one factor, proven by the WhatsApp account. So the question becomes what will be the second factor? According to security standards, the options for a second factor are something you have, something you know, like a password, and something you are such as a biometric.
