Problem statement
When using the Phone MFA factor configured for the tenant and using Twilio as the provider, there is a need to slow down the MFA voice message that plays.
Solution
Under Security > Multi-Factor Auth > Factors “Phone Message” > In the Enrollment Template and Verification Template, you can add {{pause}} in the scripts.
Each {{pause}} parameter in the template will add a 1-second delay. That’s what Auth0 can offer currently. We don’t have the feature to support TwiML scripts in Auth0.
You can use {{pause}} to add delays between words. However, for the authorization code, such as 123456, we can not add delays between the digits.
