Earlier this year allauth released a code-based login method.

1. User requests login by inputting their email address
2. Frontend sends request to dj-rest-auth's endpoint /login/code/
3. A session gets generated (similar to the email verification flow)
4. User receives an email with a random 6 character code (as per allauth)
5. User inputs that code in the frontend.
6. Frontend sends request to dj-rest-auth's endpoint /login/code/confirm/
7. Backend logs the user in (or not)

This issue is a placeholder to keep track of the progress and discussion

Planning to create a pull request for this as soon as I can.
