TNEW and the "Forgot Login..." button in the constituent record

Hi all,

My Google-fu has come up short on this one. We used to be able to reset constituents' passwords and send them a token to create a new one by using the "Forgot Login..." button on their login record in the "Contact Details" tab. Last year, we moved to a TNEW site, but have lost the institutional knowledge of how that email is even set up, yet alone if we can reset passwords through it for TNEW logins. Does anyone know if there's a way to set this up, or do we have to keep directing patrons to the login page and tell them to pretend they forgot their password when we want to attach a login to an already-existing constituent record?
