Make Authentication Easy with ‘Sign in with CSE JnU’

Building a project for your department and worried about authentication? Making sure only real students can log in can be tough. But with ‘Sign in with CSE JnU’, you don’t have to worry anymore!

This feature allows students to log in using their CSE JnU accounts. It’s simple, automatic, and updates their data whenever they update their profile on the main site. The best part? No need to write extra code to check if they’re valid students. Just follow these two easy steps:

Step 1: Redirect Users to the Auth Server

When a user wants to sign in, send them to the Auth server. Include a callback URL, so the Auth server knows where to send them back after login. For example:

http://auth.itrrc.com/?callback=https://yoursite.com/success.html

If the user enters the correct username and password, they’ll be redirected back to your site with a token attached to the URL, like this:

https://yoursite.com/success.html?token=ey....xyz

Step 2: Verify the Token on Your Backend

After the user lands back on your site, grab the token from the URL. Now, verify the token by sending it to the Auth server:

http://auth.itrrc.com/verify?token=ey....xyz

If the token is valid, you’ll get a response like this:

{
  "valid": true,
  "payload": {
    "name": "MT ASFI",
    "email": "asfi@gmail.com",
    "meta": {
      "role": "student",
      "student_id": "B2003051234",
      "batch": "1",
      "cr": false,
      "graduated": false,
      "job_description": "Software Engineer",
      "blood_type": "A+",
      "birthday": "1/12",
      "gender": "Male",
      "linkedin": "https://linkedin.com/",
      "photo": "https://blog.com/profile_photo.jpg"
    },
    "iat": 1737215096,
    "exp": 1737218696
  }
}

If the token is invalid, you’ll get a response like this:

{
  "valid": false,
  "message": "Invalid signature"
}
