2FA

2FA helps one quickly set up a backend to integrate 2 Factor Authentication into their existing workflow.

P.S Inspired from Brad Traversy's video on the same (https://www.youtube.com/watch?v=KQya9i6czhM)

Setup

1. Clone the repository
2. Install the npm packages
3. Rename .env.exmaple to .env
4. Create a file in the root directory of your project and name it TrialDB.json

Usage

As this is only the backend, you'd have to use an API testing tool like Postman. You'd also need a 2FA app like Google Authenticator (or it's chrome extension). Send a POST request to /api/register to register a new user. If successful, you'd get a JSON response with an ID and secret. Use this secret in the 2FA app/extension to get the intial verification code. Using the id and the code from previous step, send a POST request to /api/verify with the request body structured as JSON using the template

{
  "userId": "id",
  "token": "code"
}

You are all set up! Send POST requests generated from the app/extension to /api/validate replacing the token above with the code generated.
