Meet customers where they already are.
Verified messaging is not another place to send a one-time code. It is a place where the sender is known, the request is explicit, and the customer can approve or decline in one step.
Can messaging apps be used for customer authentication?
Yes. Apple Messages for Business, WhatsApp and RCS for Business each support a verified business sender and structured, interactive messages, which makes them suitable for verification and approval rather than only code delivery. Availability depends on the customer's device and country and on the approvals the business holds for each channel.
A conversation carries more trust than a code.
The value is not the delivery mechanism. It is that the customer can tell who is asking.
The sender is known
A verified business identity in the customer's messaging app replaces an anonymous short code they have no way to check.
The request is explicit
Instead of a bare number, the customer sees what is being asked — a sign-in, a payment, a change to their account.
Richer than a code
Buttons, structured prompts and a readable history, rather than six digits to copy across apps.
One thread, not a fresh challenge
The conversation persists, so a later request arrives in a place the customer already recognises.
Four places a customer can verify.

Assure is designed to use the best channel a customer's device and the business's approvals allow, and to fall back to a standard text message when no richer channel is available.
No channel is universally available. Device support, carrier support, country availability and platform approval all vary, and none of it is within a customer's control — so nobody is asked to pick a messaging app. Assure claims no carrier, Apple, Meta or Google partnership or approval, and makes no guarantee of message delivery.
Clear, transactional, and easy to stop.
Authentication content stays transactional
A verification or approval message says who is asking, what is being approved and what to do next. Nothing else rides along with it.
Marketing consent is separate
Consent to receive operational and authentication messages is not consent to receive marketing, and the two are never bundled.
Opt-in and opt-out are explicit
Customers opt in knowingly, can ask for help, and can stop messages at any time. The wording states the sender, the frequency and that message and data rates may apply.
