Auth0: unable to find ways to customize "new universal login pages"

Question

General need

• customize the MFA widget using the new universal login flow
• this is not equal to classic flow (where we have Auth0MFAWidget with a range of options as listed here)

Specific need (for the new universal login flow, not the classic universal login flow)

• Is there a possibility to change the default country on the MFA-SMS enrollment prompt?
• can we restrict the list of countries also?
• below is the page that I am looking at, can be accessed here:

Note:

• Asking these for the new universal login flow, not the classic universal login flow

Answer 1

I raised a support ticket (from a paid company account) and got a reply:

Is there a possibility to change the default country on the MFA-SMS enrollment prompt?

• it is auto selected based on the ip of the user

Can we restrict the list of countries also?

• not available
• workaround is to use JavaScript on the universal-page-template which hides specific countries using the DOM
• something like:

    const allList = document.getElementsByTagName("ul")[0];

    Object.keys(allList.children).map(ch => { 
        if (allList.children[ch].innerText.search('Japan') !== -1){
        allList.children[ch].style.display = none;
        }
    });
