So, I will show how you can make a custom email verification mechanism using Django API and React as front-end. For your information, you can follow the same techniques for forgot password. Below steps need to be followed.

1. Click submit button in the register form
2. After creating the user in Database, a verification mail is sent to the user email address. The verification email link contains a random token. The token will expire after a fixed amount of time.
3. User click the verify button in his/her email message
4. The back-end checks the token validity and sends a response to the front-end

Sending Verification Email To User

At first, getting front-end URL from .env file (.env file = where all constant values of the application are stored). Then, generating a token by get_random_string.

Both the front-end URL and the token combine to create the verification email link. This link is attached to the email template. Finally, the email is sent to the registered user.

In my case, the email is looked like below

Look at the link in the above image. It follows the below format.

<frontend-url>/email-verify/<random-token>

The back-end part is done till now by sending the verification email to the front-end.

Now the front-end part comes into the play.
