Which UI do you use?

Custom UI

Pre built UI

smsDelivery

• Using your Twilio account
• SuperTokens SMS service
• Custom method with full control

By default, if nothing is configured, the SDK will send SMSs using our APIs (https://api.supertokens.com). This is rate limited and is only meant for development / demo purposes.

You can learn more about each of these methods in the "SMS Delivery" section under "Auth Flow Customizations" (find it in the navigation list on the left).
