Hi @mike.huebner

Welcome to the Auth0 Community!

I am sorry about the delayed response to your issue!

What are the add commands you have used in order to add the aforementioned screens?
The commands should be:

  auth0 acul screen add mfa-otp mfa-otp-challenge -d {{ACUL_APP}}
  auth0 acul screen add mfa-sms / mfa-sms-challenge -d {{ACUL_APP}}

Additionally, just to double check, have you checked our documentation on setting up ACUL and have you authenticated against your tenant via auth0 login?

Alternatively, you can try running these commands to save the templates locally:

auth0 acul screens show mfa-otp-challenge > mfa-otp-challenge.html
auth0 acul screens show mfa-sms-challenge > mfa-sms-challenge.html

Once you have done so, you should be able to modify the files in order to add your custom links and deploy them using:

auth0 acul screens update mfa-otp-challenge --html mfa-otp-challenge.html
auth0 acul screens update mfa-sms-challenge --html mfa-sms-challenge.html

If you can provide some additional information as to how you have configured the ACUL CLI, that would be helpful to troubleshoot the issue that you are having.

Kind Regards,
Nik
