Authenticate with SMS

While this SDK is still supported, we recommend using newer JavaScript SDK, which is optimized for React Native, but also comes with a host of other benefits.

Dashboard Configuration

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.

React Native provides SMS authentication through the dynamic client’s auth methods. You can send OTP codes and verify them programmatically.

React Native

import { dynamicClient } from '<path to client file>';

await dynamicClient.auth.sms.sendOTP({
  dialCode: '1',
  iso2: 'us',
  phone: '2793334444',
});

// Later, verify:
await dynamicClient.auth.sms.verifyOTP('received-token');

// Resend if needed:
await dynamicClient.auth.sms.resendOTP();
