Is your feature request related to a problem? Please describe.

Joomla has events for all steps in a password reset chain except for the confirmation step.

Our site are using both email address and username for logons. But the username is hidden everywhere on the site.

When I use wants to reset their password they don't know what the randomly generated username is for the confirmation step.

Describe the solution you'd like

A before plugin event before the username checkup would help us with checking up the username from the email address and change the form data.
