How to implement OTP based verification before letting the user to create a new password using pyotp?
I am very new to Django rest framework. I am building APIs for my mobile application. In Forgot password module, I have the below flow 1 - Ask user to enter mobile 2 - check existence 3 - If exists - > send OTP 4 - Verify and let user create a new password. But in this case, I would like to know the way of handle the below situation. When one user requests otp and waiting for it to verify , meanwhile another user requests for OTP At this time, how to handle the both user ? I thought of 1 - creating the dictionary and save the user id as key and otp as value in views.py to verify particular user . 2 - store the otp temporarily until it verifies. Kindly let me know which is the secured way and any alternative for this kind of scenario -

Authenticate Public APIs with HMAC and Cloudflare?

Using custom models.py module name with custom user account app in Django
I have a custom user account model which I use in the settings like so; AUTH_USER_MODEL = 'user_account.UserAccount' This obviously refers to user_account.models.UserAccount model class. Though, I would like to rename the models.py module to user_account_models.py, in which case django naturally complains about user_account.UserAccount not being exist. I've checked the doc, and models are stated in app.ModelName format, nothing in between to refer to where the model is "since django assumes they will always be in models.py in every app" I assume. Is there a way to make django use custom names for models.py module (or any module for that matter) for a particular app (since every app will have it's own distinctive name with the app name as prefix)? -

How to create management command to email a password reset?
Using the django-oauth-toolkit, I have to create a management command that would send a password reset email off to an email address.

CKEditor deleting <video> tags
I've added some tags in a CKEditor instance using the following code (loading from a Django-AJAX request). let newEl = CKEDITOR.dom.element.createFromHtml( `<video height='320' width='500' controls autoplay playsinline src='${url}'></video>` ); CKEDITOR.instances.q_body.insertElement(newEl); It loads correctly in the browser, but on hitting save, and after going to the same page, every video tag has been stripped out and no longer renders. I've tried numerous attempts and plugins, but nothing is working. I'll appreciate any help with this. -
