- Welcome to this comprehensive RUclips tutorial on implementing JWT (JSON Web Token) Authentication in ASP.NET Core 7 Web API. In this video, we'll guide you through the process of adding a robust and secure authentication mechanism to your API using JWTs.
JWT Authentication is a popular method for securing APIs due to its compactness, self-contained nature, and efficient validation process. It enables you to transmit user identity, roles, and permissions within a token, making it an excellent choice for modern application architectures.
Key Takeaways:
Understanding JWT Authentication: Get a clear understanding of what JWT Authentication is and why it's a popular choice for securing APIs.
Installing Required Packages: Learn how to install and configure the necessary NuGet packages for JWT Authentication in your ASP.NET Core 7 project.
Configuring Authentication: Explore how to configure JWT Authentication in the program.cs file using the AddAuthentication method.
Configuring JWT Options: Set up JWT options such as issuer, audience, signing key, and clock skew to ensure secure token generation and validation.
Securing Endpoints: Discover how to use the [Authorize] attribute to secure specific endpoints, allowing access only to authenticated users.
Token Generation: Learn how to generate JWTs after successful user authentication, and understand the structure of a JWT.
Token Validation: See how the JwtBearer middleware automatically validates JWTs, ensuring the token's integrity and authenticity.
Testing JWT Authentication: Use tools like Postman to test your JWT Authentication implementation and observe the results.
Best Practices for JWT Security: Learn about security best practices when using JWTs, including token expiration, refresh tokens, and token storage.
Decoding JWT Payload: Understand how to decode and interpret the claims contained within a JWT for debugging and auditing purposes.
By the end of this tutorial, you'll have a solid grasp of implementing JWT Authentication in your ASP.NET Core 7 Web API. Whether you're building a RESTful API for a single-page application or a mobile app, JWT Authentication offers a powerful and flexible way to ensure secure communication between clients and servers.

very informative. excellent
Glad it was helpful!
very nicely expalin sir..best on you tube for .net
Thanks for your kind words. 🙏❤️😊
Very good Explanation!
Glad it was helpful!
Excellent explanation 🎉
🙏 Thanks 👍
@@tech_yatra thank you for your reply sir. Your explanation is very easy to understand. One request to you, Could you pleae make video on microservices in c# like
API gateway
Authorization and authentication microservices
Comunicate microservices each other
Sure, I will make.
muchas gracias Mister muy bien explicado......
Me alegro que te guste esto. muchas gracias por tus amables palabras.
Bro mera token swagger pe nhi aa rha hai but mai debugger lagaakar check kar rha hu to generate ho rha hai can you explain why did happen bro mai 2 din se try kar rha hu but swagger pe show hi nhi ho rha hai token😢😢
nice keep uploading videos
Thank you, I will
Well explained viseo, could you please make Refresh JWT Token video also.
Or if you already make please share video link.
Thanks
Sure this is in my list
Well explained, could you please explain it using stored procedure and password hashing
Sure I will make a video on this soon.
Thanks
🤗
❤
nice tutorial
🤘
Thanks 🙏👍 kindly like share and subscribe.
How do we validate this token i mean what if we make change in this generated token how we know that this is not the correct token
Could you please create video on refresh token?
Sure I will create
good explanation.
I have a query regarding where to use?
1. If we use gRPC, are we not repeating model information? one in our .NET or Java application and same model in proto buff file?
2. If I use in in Authentication api, so is flow like below
Ocelot -> Authentication Microservice -> gRPC client code -> gRPC server ?
Thanks for your question!
Yes, in gRPC, the model is defined twice - once in your .NET/Java app and once in the protobuf file. The protobuf helps in fast and efficient communication between services, even if it seems like repetition.
Your flow looks correct: Ocelot -> Authentication Microservice -> gRPC client -> gRPC server.
hum Userwise database create karke. connection string change kar sakte hai login time par?
Hi Nishant how r u. pls help Employee data which we are getting by consuming this api as in video and HOW we post it into another api Employee table whose column are different from out db employee column? how we mapp out employeeModel and other api employeeModel.
To map Employee data to another API with different columns, use a mapping library like AutoMapper. Define a mapping between your EmployeeModel and the target API's EmployeeModel.
After mapping, use HttpClient to send a POST request to the other API with the mapped data.
Feel free to ask if you have more questions!
How to generate key dynamically.. here we are hardcoding which is not secure
Thanks for your comment! Generating keys dynamically for Jwt authentication in .NET 7 Web API is a great consideration for improved security. To achieve this dynamically, you can explore using a secure key generation mechanism, perhaps leveraging libraries like System.Security.Cryptography.
I appreciate your emphasis on security, and I'll definitely consider creating content on dynamic key generation in an upcoming video. Feel free to subscribe for updates!
If you have any more questions or suggestions, please let me know.
how you created jwt key, issuer, audience and subject json?
The values for the audience, issuer, and subject in a JWT are typically determined based on your application's context and requirements
Issuer (iss): "my-app"
Audience (aud): "my-app-users"
Subject (sub): "user123"
Values:
Issuer (iss): "my-app"
Audience (aud): "my-app-users"
Subject (sub): "user123"
Code:
javascript
Copy code
const jwt = require('jsonwebtoken');
const payload = {
sub: 'user123',
iss: 'my-app',
aud: 'my-app-users',
exp: Math.floor(Date.now() / 1000) + (60 * 60)
};
const secretKey = 'your-secret-key';
const token = jwt.sign(payload, secretKey);
console.log(token);
Hello Nishant, Very well explained , thanks for this. Can you please tell me how can we get the Jwt to configure in Appsettings.json file, how did you get that key ,issuer and audience?
This information will be used later to generate a JSON Web Token. Note that you can give any name to this section you want. You can use www.random.org/strings to generate random strings. Make sure you are not doing this for production
If you have any other questions feel free to ask. Thank you
@@tech_yatra : Yes please, I want to know how you got this values of Key, Issuer, Audience. Please guide me. Its very grateful you saw my message and responding.

Authentication hone ke bad jo JWT token generate hoga use kaha store karna chahiye frontend me take next time protected API ko call karte time use kar sake... Please help me to get answer for this.
JWT token ko securely store karne ke liye localStorage, sessionStorage, ya httpOnly cookies use kar sakte hain. HttpOnly cookies sabse secure hain kyunki ye XSS attacks se bachata hai. Hope this helps.
JWT token ko front-end me store karne ke liye, aap localStorage, sessionStorage, ya httpOnly cookies ka istemal kar sakte hain.localStorage aur sessionStorage JavaScript se accessible hote hain jabki httpOnly cookies XSS attacks se bachate hain.
@@tech_yatra thanks a lot for replying. Agar ho sake to ek short video is topic pe bhi bana dijiye is topic pe clear information wali video nahi hai. 🙏🏻♥️
very informative. can you try to make video on auth0?

Hello sir .token jb expire hota h to phir vo generate kaise hota h ?
Jab JWT token expire ho jata hai, server-side logic naya token generate karta hai. Yeh process server policies aur client interaction par depend karta hai. Agar kuch aur poochna hai, feel free to ask!
Like agr mai continuously work kr rha hu...token expire time 20 minutes.after 20 minutes kya hoga?
Refresh tokens are the kind of tokens that can be used to get new access tokens. When the access tokens expire, we can use refresh tokens to get a new access token from the authentication controller.
Thank you sir
Sir I have one question regarding dot net ...how to convert database table result to image format in aap net core web api ?
Bhai iska database ka script mil sakta hai kya please?
I do not have a db script. You can do the migration as I did by following the same steps.
