Implementing OTP Based Verification for User Password Resets in Django REST Framework

In today’s digital landscape, ensuring the security of user accounts is more critical than ever. One common practice to enhance security during the password reset process is the implementation of One-Time Passwords (OTPs). This guide will guide you through the process of implementing OTP based verification in your Django REST framework application, especially for your mobile app’s forgot password module.

The Problem

As a developer, you will encounter a situation where users can request an OTP to reset their passwords. However, complications can arise when multiple users request OTPs simultaneously. Here’s a brief outline of the process you want to achieve:

Ask the user to enter their mobile number.

Check the existence of the account associated with the mobile number.

If it exists, send an OTP to the user.

Verify the OTP before allowing the user to create a new password.

Your challenge is how to handle scenarios where multiple users request OTPs at the same time. Specifically:

How do you ensure that OTP requests are processed correctly without causing conflicts?

How do you maintain efficiency and security in the verification process?

Proposed Solution

To tackle the OTP verification process efficiently and securely, you can implement a simple yet effective solution using Django’s ORM. Here's a step-by-step guide:

Step 1: Create a Database Model for OTPs

First, you need a database model that stores the OTPs associated with each user. You can create a model in your models.py file like this:

User: This foreign key links the OTP to a specific user.

Code: A randomly generated OTP that will be sent to the user.

Create Date: Automatically records when the OTP was created.

Used Date: Records if and when the OTP was used, allowing for verification.

Step 2: Generate and Send OTP

Once a user has requested a password reset, you create an entry in the UserOTP table. A typical method for generating an OTP could look like this:

You then send this OTP to the user via their preferred communication channel, such as SMS or email.

Step 3: Verification Endpoint

Create an endpoint that accepts the OTP and the user ID. This endpoint will handle the verification process, checking:

If the OTP is associated with the user.

If the OTP is still valid (not expired or used).

Conclusion

Implementing OTP based verification in a Django REST framework application can significantly improve the security of your password reset functionality. By creating a dedicated model for OTPs and ensuring proper checks during the verification phase, you can handle multiple OTP requests efficiently and securely.

As you build your application, remember to always prioritize both user experience and data security. With these practices in place, your users can feel confident that their accounts are safe, even in situations where many users are attempting to reset passwords at once.

Implementing OTPs may seem complex at first, but with the right approach and tools, it becomes a straightforward addition to your authentication processes.
