Bypassing 2FA in GraphQL APIs: A Step-by-Step Guide

This blog explains how 2FA can be bypassed in GraphQL applications using different techniques.

What is GraphQL?

GraphQL is a query language developed by Facebook for APIs. It let’s user fetch exactly the data they need through a single endpoint (usually /graphql). The client decide the structure of the response making it highly flexible for applications.

Example query:

query {
  user(id: "123") {
    name
    email
  }
}

Two-Factor Authentication (2FA) is a common security measure that adds an extra layer of protection to user accounts. It works by requiring two types of information: something you know, like a password, and something you have, like a one-time password (OTP) sent via SMS, email, or an authenticator app.
