Hey everyone I want to share my personal and real-world experience about credential stuffing attacks. These are very hard to solve because fundamentally it's users fault, especially the ones with password-reuse habit. Nevertheless we responsible developers are the ones who should keep the internet safe, so feel free to chime in, evaluate my solutions and maybe we come up with "the" best practice against this type of attacks.

If there's interest I want to make this into a library and open source a django-specific solution as it's my everyday framework. The discussion applies to ALL web frameworks.

Hi! Normally when you rotate secret key, users are logged out, which is a big inconvenience if you have millions of users and might cost your business valuable users, and this pushes companies not to rotate keys, which is not the best practice..

that's why I wanted to make this process transparent to the user, I created a library "django-rotate-secret-key" which helps you rotate your secret key and still accept sessions with the old key for limited amount of time, and I explained how to use in this medium post.

obviously this is not something you want if your key is compromised, but if you want to rotate just as a best security practice this library is for you!

what I love about this library is, once you pass that window where you accept both keys, you can delete/revert everything so there is no residue with this solution! not a single line of code you need to maintain in the future.

Feedbacks welcome, thank you very much!

looks amazing! keep it up

great idea, which also warns about the websites it won't work on.

some require session authentication, so bot needs to login and THEN verify.

Thanks for seeing the value, after releasing this I got to know some services require session authentication, so without your password (or cookies) the bot cannot verify.

I think this was a nice experiment and still usable for many services.

you make a very good point, thanks for the warning.

I will open source whenever I have time, I just did it last night and decided to share.

For future awesomeness please follow @eralpbayraktar on Twitter :)

Thanks!
