There are views for every auth related use case except for sign up:
I don’t know. Maybe check the ticket tracker for any open or closed tickets?
Also this package is very popular and has built in signup flow: https://django-allauth.readthedocs.io/en/latest/
If I remember right, signup was always the part of auth that was the most opinionated - especially in what you capture - so we never made a signup view (especially as there’s plenty of third-party solutions). That said, it is a little weird that login is there but signup is not.
