Twilio has announced the General Availability of its Verify Push service, a fully-managed API solution for verifying users across multiple channels without the risks and costs associated with One-time Passcodes. This service enables in-app user verification via a push notification, allowing businesses to build secure engagements into their application flows while reducing friction for better UX and increasing security. With Verify Push, customers can provide an alternate channel to their verification flow, such as a push authentication to their linked device to confirm transactions, providing a countermeasure to prevent unauthorized activity. The service is turnkey and ready to deploy, built on public key cryptography, and provides detailed information about each verification, including request status, device name, and other valuable signals. It also offers predictable costs by eliminating the uncertainty of international telephony costs.
