​
Dashboard Configuration

Toggle on “Phone Number” in the Log in & User Profile section of the dashboard.
By default, you can use Dynamics credentials to send SMS messages to your users. However, if you want to send beyond US & Canada, you will need to set up your own Twilio account. In order to do this, you toggle off “Use Dynamic’s credentials” and a section will open up for you, where you can enter your own credentials.

​
SMS & Embedded Wallets

When you enable SMS sign-up, you can also enable embedded wallets for your users. This means that when a user signs up with their phone number, they will also receive a wallet that they can use to interact with your application. In order to ensure your end users are adequately protected against attacks like sim swaps, we highly encourage you to enable account MFA (TOTP) via Google Authenticator.

​
Prerequisites

  • You need to have the Dynamic Client initialized (See this guide on how to do that).

​
Usage

import {
  sendSmsOTP,
  verifyOTP
} from '@dynamic-labs-sdk/client';

// With the user's phone number, call sendSmsOTP to get the otpVerification
// Then, once the user inputs the OTP code, call verifyOTP to verify it and complete the authentication

let otpVerification = null

const singInWithPhone = async () => {
  // Replace 'US' with the user's country code and '1234567890' with the user's phone number
  otpVerification = await sendSmsOTP({ isoCountryCode: 'US', phoneNumber: '1234567890' });
  // Store the otpVerification for later use with the verifyOTP function
};

const verifyOTP = async () => {
  // Use the same otpVerification object that you got from the sendSmsOTP function
  // Replace '123456' with the OTP code entered by the user
  await verifyOTP({ otpVerification, otp: '123456' });
};
