One of the common questions received yesterday (9/7/17) after launching MFA was from site administrators or volunteers with a security template allowing access to Configuration>Preparer Setup.
Scenario: I have multiple volunteers at my site that also volunteer at other sites. When I access my own Preparer(s) Setup Menu page, I can see the checkbox to allow my e-mail address to be used across multiple accounts. However, when I access the Preparer(s) Setup Menu page for other volunteers at my site, I do not see the checkbox under their e-mail address entry field.
Q1: Why can’t I see the checkbox for my volunteers?
A1: The reason you are able to see the checkbox under your Preparer(s) Setup Menu page is because you completed the Account Update screen after MFA was launched. As each volunteer completes the Account Update screen for their username, the checkbox will be available within their Preparer(s) Setup Menu page.
