Credential stuffing and recovery calls have dropped to near-zero since we replaced SMS with WhatsApp and passkeys.
WhatsApp OTP builds trust with encryption, verified senders, and global reach.
We know SMS costs can sting - especially when you’re scaling. With over 2.7 billion users, WhatsApp is a trusted, low-cost channel you customers already use daily. Use this tool to see how much you could save by making the switch.
Use Authsignal’s pre-built UI and SDKs to add WhatsApp OTP in hours, not weeks. Add to your existing identity stack, like Cognito, Keycloak, Azure AD B2C and more.
SMS verification is unreliable and expensive. Authsignal’s WhatsApp OTP solution ensures consistent, fast delivery at a fraction of the cost.
Authsignal integrates with your messaging platform, such as Bird.com or Twilio, to handle the delivery of WhatsApp OTPs.

How do I work with Authsignal?
Authsignal is a drop-in authentication layer that integrates into your existing identity stack (such as Keycloak, Azure B2C, Cognito, or custom stack). You integrate via simple APIs or SDKs, configure your authentication flows through our no-code dashboard, and start sending OTPs via WhatsApp with minimal engineering effort.
How does WhatsApp work with my authentication flow?
When a user requests a login or verification code, Authsignal automatically sends the OTP to their WhatsApp account via a verified business sender. You can set WhatsApp as the primary channel and fall back to SMS or email if WhatsApp isn’t available.
How much can we save from switching to WhatsApp SMS from SMS?
Customers can see up to 90% cost savings when switching the majority of OTP delivery from SMS to WhatsApp. WhatsApp messages are significantly cheaper. Actual savings depend on your user base, geographies, and fallback rates, but the ROI is generally substantial for countries in high SMS regions.
How fast can we deploy WhatsApp SMS with Authsignal?
Most customers deploy WhatsApp OTP in a few days to a few weeks, depending on complexity. If you already have WhatsApp Business APIs or verified senders set up, it's even faster. Our SDKs, no-code configuration tools, and API-first design mean you can roll out WhatsApp OTP without re-architecting your entire identity flow.
What user education is needed to support adoption rate?
Minimal to none—AirNZ didn’t need any user education for their WhatsApp OTP launch. WhatsApp already has over 3 billion active users globally, and most customers are familiar with receiving messages on the app.
Authsignal is multi-factor authentication (passwordless authentication) as a service. Focused on powering mid-market and enterprise businesses to rapidly deploy optimized good customer flows that enable a flexible and risk-based approach to authentication.
