SMS Configuration

​

Setting up SMS

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 also require a second factor before the wallet is generated. This can be a passkey, or a one time code. We highly recommend using passkeys, which shortens the onboarding flow.

If however, the user loses or deletes their passkey, they will be locked out of their wallet. To prevent this, we recommend prompting users to add an email address to their account. This way, they can recover their wallet if they lose their passkey. When using one time codes, the user will automatically prompted to add their email.
