JWT Authentication in NodeJS 

I have seen the playlist of million subscriptions of the channel. but your teaching style and explanation is great.

the thing is the way you make us understand the concept are so good. In previous video you thought how to implement cookies but i never got time to watch the whole video but i created a logic by myself to delete the cookie id when a user clicks logout such that it redirects me to the login page again. Thank you so much and keep up the good work!!

All of videos from this guy are very useful and amazing

Stateless vs Stateful understood because of you, thanks!

thanku piyush you made my journey possible to project building

You are gem 🎉 You have very very deep knowledge of all things ❤🎉🎉

finally understand sessions cookies and jwt...thank you sirji!!!!🙏🙏🙏🙏

i like the way you explain by giving examples and your explanations are very user friendly

bahot badiya exaple de kar samajiya sir apne secret key bhot confush tha thankuu

wow excellent explaination..thank you brother for this playlist 😊

10:38 you changed the token. the email was changed, the new token contains Tcf90 at last but at 10:39 (HXfCY at last) there is a cut in video where you changed it, i was getting the glitch and sure you too but you not explained that in video and directly changed something.

❤ sir your lectures are blessings for me... plz cover advanced nodejs caching, threading, etc...

this is the best on internet

Awesome explanation bhai 👌

Very nicely explained Piyush. ! question though, in case of refresh token does the secret on the server changes since the payload information would remain the same ? Wonderful JWT explnation

Brother! as we are storing tokens with cookies. Someone can copy that token and log in, as you already demonstrated. Is it a secure way? कृपया मार्गदर्शन करें..

Great video sir👍

There is no login if you changed the email using secret password also. at 10:38 to 10:39 even he can't login. there is a cut in the video from 10:38 to 10:39 where somehow he got loggedIn,the funny thing is at 10:38 the token he copied frow jwt is different from 10:39 (where there is a cutshot in the video) and he got login.

I really like his vs code theme , did anyone know the name of it ?

this is only video in which i saw that the use secret key in jwt ♥ thanks ♥

Nice video

Great video bhaiya there is something csrf is jwt secure with that hack ?

Keep Going Bro. You Doing Well

But if we store sessions in database tab to problem ni hogi na in statefull

Great explanation! 👌

wow, awesome bro

Bhaiya jab tokens ko cookies me store kiya ho to react js ke routes ko kaise protect kare based on presence of token in cookie?

JWT Authentication basic to Advance full cover karado sir.

Thank you bhai...... ❤🧡💛💚

Assalamo Alikum Sir Sir kiya asa office hai jo urdu mai interview ly our office waly urdu bholy muje typescript react javascript and node.js and exprees ati sirf language ka issues hai english ki samj ati par mai bol nhi sakti

Thanks

Sir when you are starting a complete react JS course basic to advance any idea sir?

hello big brother what is the difference between jwt token vs express-session ?

Sir I really like your videos but there are 2 problems which I am facing: 1. Your authentication videos are dependent on URLGeneration videos. 2. If someone face any error in the URL at any point he wont be able to continue until that error gets resolved. 3. Solution : if you could provide the source code then it would be easier for us to resolve our errors. 4. Solution : If you could make such videos which are not dependent on each other then it would be easier for us to understand each concept from the Scratch

sir i am getting error "jwt malformed" i tried matching codes, also searched on stackoverflow but just couldnt solve the error...please help if you know...i will update if i get the solutain

I dont know why everytime its giving me error as jwt malformed but i am writing the same code as you have written .. I have seen your all videos upto authentication and everything is fine but i dont know why as soon as i am using jwt its not working . i am working on it to find error from past 2 hours but its not working please help

Thx sir❤❤

Thanks bro

when i replace my token with wrong one the app remain run

4:30 difference between this token and the UID

Too Good

Where we are calling getUser function?

Hmne Information (Object) ko JWT ki madad se bina Secret key bhi generate kar diya to ye secret key kiss kam ki? Plz Reply Sir...

thanks

nodejs\urlshortener\service\auth.js:8 _id: user._id, ^ TypeError: Cannot read properties of undefined (reading '_id')

but somewone steal the cookie and try to login in their system can we stop this

how on changing payload with wrong email and right secret key, we logged in at 10:40

Please mention it's Hindi in title.

jwt itma hi hota he ya aur bhi kuch he

helpfull

bro where is the code

then why the heck IRCTC uses session😂 it loggs you out at the last second of your attempt to book tatkal ticket💩

let say you want to make this project open source, but in the backend itself you shared the secret key and using that anyone can get make fake token????

someone has its source code

explaination is top-notch but appke voice tone like a little child is speaks

hey I am here on 1st jan anybody else?
