Verify logins and transactions with one-time passwords by SMS.
SMS OTP adds one-time-password delivery to your software. A user enters a mobile number, receives a code by SMS and verifies it to log in or confirm an action. Our own products already use OTP login, so the flow, the limits and the screens are familiar territory.
In the current builds of several of our products OTPs use a fixed code for testing. Connecting a live SMS gateway is the step that makes them production-ready, and it is what this service delivers.
