Enabling 2FA provides a higher level of security than authentication methods that depend on single-factor authentication, usually a password. In 2FA, users have to provide their password as well as a One-Time Password sent via SMS to their mobile phones, to access their account.

SignalWIre’s Communication API, powered by Relay Technology, allows to easily build and add two factor authentication in your applications, without having to make any changes to your application’s logic or database schema.

In this LIVEWire, Luca Pradovera will:

  • Explain how to use SignalWire’s Communication API to generate a One Time Password (OTP) and send it via SMS or voice to a phone number
  • Verify that the OTP entered by the user is correctly associated with the phone number and still valid
