Hi Wes,
Nothing needs to be done to activate this feature, it should already be there underneath the login box of your website. If this isn't there, can you let me know the URL of your website so I can check why this may be.
You can also access the password reset page by going to <your_website_address>/Common/Password/ForgottenPasswordRequest.aspx
