External SMS Providers
BindID SMS messages are used to send OTP verifications and CIBA links, as well as in desktop to mobile authentication flows (when requested by users). By default, BindID sends these messages but you can configure an external provider, Twilio, to send them instead. This may be useful when you want to use a custom sender phone number, already use Twilio to send other SMS messages, and with investigating issues (via the provider's logs).
Once Twilio is configured, it will be automatically used instead of the default BindID SMS service. After configuring Twilio, you should verify that SMS messages are sent as expected. If you need to restore the default BindID SMS service, go to Settings > Integrations and click Reset under SMS Provider Details.
To send SMS messages via Twilio, on the Settings > Integrations page:
- From SMS Provider Details, select Twilio from the SMS provider list.
- Fill in these fields:
- Account ID: your Twilio account SID
- Account token: your Twilio auth token
- Sender phone number: your Twilio phone number (the number from which SMS messages are sent)
- Save your changes.
