Problem
Currently if a user forgets their password, there's no way on the login/signup page for them to reset it. They have to reach out to the people in their organization who can access their local deployment and have them create a reset link for them. This can be particularly troublesome in larger organizations or for newer members who may not know who to ask. This seems like a pretty fundamental feature to have on any login page.
Solution
I don't know how your backend works so forgive me if there's more to it than this, but I would assume at minimum a "Forgot password?" link is needed on the login page that generates the reset link without manual intervention and takes the user to the reset password page.
