go-password | A Golang library for generating high-entropy random passwords similar to 1Password or LastPass | Generator Utils library

I have a Django site which is hosted on GCP App Engine with SendGrid as email host. When resetting the password and clicking on the link in the following email, the subsequent error is thrown:

Your connection is not private
NET::ERR_CERT_COMMON_NAME_INVALID

I've looked into several potential causes (linked at the end) but haven't been able to find a solution.

password_reset_email.html (only displaying the reset_link block)

I'm trying to create this sliding sign in /sign up portal but the original code was on Vanilla JS. The components seems unmounted on the Dom and the program is unable to find the Classlist by its id.I did few attempts on using Component did mount but it is throwing error, later I've found out that I am lacking understanding about Class vs function on react. componentDidMount() seems to be only for Classes. Now I cant seem to find a valid solution for this. Also I might forget, when should I really need to use Classes vs functions in rendering a component? How can I prevent calling an unmounted element in the DOM if I use function instead of class?

This is the raw Html,css,vanilla js code for the portal.

I have almost completed adding a PIN number field for users in the Django admin.

previous question

I have a separate form to change the PIN number, very similar to that seen when changing a password. I have an issue with the successful redirect after a form submit. I would like to redirect back to the user change form, but have been able to do so.

What is the url pattern required to redirect to that page on a successful redirect? When submitting a new password successfully you can redirect back to the user change page therefore it is possible.
