JWT Authentication in NodeJS

[@tfnt3839]

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

All of videos from this guy are very useful and amazing

[@dhruvsolanki4473]

Stateless vs Stateful understood because of you, thanks!

[@ctauheedpasha1527]

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!!

[@omprakashshaw796]

Completed half of the playlist , thank for explaing things so easily ❤❤

[@Shashwat-000]

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.

[@tgayush1424]

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

[@AfhamAdian]

this is the best on internet

[@Powerful-Manifestor-]

Hey! Great explanation! I have a couple of queries: 1. How stateful approach is taking memory on server? In the end, we used DB instead of map, right? And anyhow, we do store createdBy anyways. So mainly is logout the issue? 2. Also, in stateful, why does logout happen even after persisting createdBy to DB?

[@Shashwat-000]

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.

[@Black-Curtains]

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..

[@deepanshuaggarwal5181]

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

[@Ayush37262]

Did you got the answer?? I think maybe because we have already entered the correct email and password in the beginning...

[@ayushacharya4778]

For that you need to know how jwt is verified. Header and payload part are taken and they are hashed with secret key to get a signature. First part of token is header, second is payload and third is the signature that i described how it comes. Verification(jwt.verify(token,secret): The header, payload and the secret are hashed and we get a new signature. If the new signature matches with the one we received from the third part of token(received signature) then the token is verified and user is authorized. Even if the email was changed, the newly generated token was valid. We extracted user id and So we logged in at 10:40

[@100DDC]

wow, awesome bro

[@vijenderkumar3034]

Nice video

[@amrExplore]

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

[@NKAnimations-mm2pp]

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
