[PR request] Update docs w/ more specific examples / recipe's

[derek-adair]

There are a number of ways django-allauth can be extended or otherwise customized that are not common enough to modify core / add settings (like expiring verification links).

A lot of this is documented in the advanced usage pages (accounts / socialaccount), and the FAQs are there -- but there is room for more "recipes".

I will be collecting various snippets/examples to add to the docs in an effort to help prevent superfluous issue submission.

Please comment with links to recipes/examples of extending django-allauth

• one off email verification - not implemented
• multiple user type signup forms. I have an example of this I can add.
• confirm email on password reset

I had wanted to use django-allauth-2fa but I saw that Django all-auth now has the same feature inbuilt, however, there is no explanation anywhere on how to implement the newly added 2fA feature. The documentation just barely scratches on the feature. Could someone who has been successful with it be kind enough to point me to somewhere I can get information on how to implement it in my project? I have already successfully integrated Django all-auth for both regular and social accounts. Or is it still at the early stages and not ready for usage
