How to Integrate MSG91 with Auth0

MSG91 has created a one stop solution for all Auth0 users to send Multi Factor Authentication communication(MFA) through multiple channels like Text message, Whatsapp, RCS, Emails and Voice Call. Create Automations like: If the country code is “+34” then the text message/Whatsapp/Voice/Email/RCS will be in Spanish. If the country code is “+91” then the text message/Whatsapp/Voice/Email/RCS will be in Hindi. We support such regional language automations.

MSG91 provides cloud communication services in 190+ countries with robust and easy to use APIs. For any queries, please contact support@msg91.com

To use the SMS factor, your tenant needs to have MFA enabled globally or required for specific contexts using rules. To learn how to enable the MFA feature, see:

• Enable MFA
• Customize MFA

The last steps are to configure the SMS Factor to use the custom code and test the MFA flow. Note: Once you complete the steps below, Auth0 will begin using this factor for MFA during login. Before activating this integration in production, please make sure you have configured all components correctly and verified on a test tenant.

1. Go to Dashboard > Security > Multi-factor Auth and click the Phone Message factor box.
2. In the modal that appears, select Custom for the delivery provider, then make any adjustments you’d like to the templates. Click Save when complete, and close the modal.
3. Enable the SMS factor using the toggle switch to begin using this factor.

Trigger an MFA flow and verify that everything works as intended.

If you do not receive the text message, look at the tenant logs. Look for a failed SMS log entry. To learn which event types to search, see the Log Event Type Code list, or you can use the Filter control to find MFA errors.

Make sure that:

• The Action is in the Send Phone Message flow.
• The secrets are the same ones you created in the steps above.
• Your MSG91 account is active (not suspended).
• Your phone number is formatted using the E.164 format.
