OAuth terminologies and flows explained - OAuth tutorial - Java Brains

In this tutorial, you’ll learn a couple of things. First you’ll learn about some key key terminologies used in OAuth. These are terms you will encounter in OAuth implementations, articles and pretty much anything to do with OAuth. And once you have learned that, you will understand how some of the important OAuth flows work in detail. OAuth has a lot of different variety of flows, but there are few key ones that you really should be knowing. Which you will by the end of this tutorial.

Nobel Prize-winning physicist, Richard Feynman had once said: “You know you have mastered a skill, when you can teach it to a child”. Why? Because it forces yourself to understand the concept at a deeper level and simplify relationships and connections between ideas. Great Job Koushik! Thanks.

How different it is from SAML

you all probably dont give a shit but does any of you know of a tool to log back into an Instagram account..? I somehow forgot my password. I would love any assistance you can give me.

The tutorial is too good to having clearer view on Oauth flows. Hats off to the author

I just don't understand why some people would thumb down on this tutorial. In fact, all the tutorials from this channel are excellent. I learned a lot from them

Hands down the best style of introducing technical material, that I have ever seen. Your videos are so easy to follow. I'm glad you start with concepts and examples, before going into the jargon.

Accidently found one video by Java brains, and this is my fifth video back to back, so additive ( things I understood in past with partial knowledge and getting confused time and again, explained o me here like a baby). I have seen many videos but no one explained like you did. Thanks a ton. Please put a link where views can make some donations if they are happy. I would love to do that

[@harrywang6792]

Thank you!!!! I never know what "client" site means until now. There are so many things on the internet, and unfortunately people just assume it's common knowledge and don't bother explain them, which makes the process so much harder and frustrating. Thank you for taking the time

[@tarknural5963]

Client in any concept is the service(person, program, computer, platform) that requests something from some distributed remote server.

[@danielhaile9073]

Thanks for making it simple to understand the big concept .

Great explanation Kaushik! The animations makes the illustrations way better. I would love to see you do a system design playlist which can go over the web architecture and design of various large scale applications like Netflix, Uber and Facebook. Most videos on youtube are done on the white board. It will be great if you can do one with animations. Thanks!

[@elephant742]

Hi Kaushik. Thanks a lot for providing such great content. You are doing great service to the community. Can you please release few videos on saml as well ? What is saml and how does it differ from oauth and how to implement it using spring boot .

[@andrewbutz5590]

Thanks, very helpful video! A few questions on the third flow, Client Credentials: 1. You mention that micro service 2 has an authentication server. But in the terminology we only talked about an authorization server--is this indeed a different thing, or did you mean to say authorization and not authentication? 2. In the second step, after MS1 goes to the MS2 Auth server, it receives an access token for, you say, only the API calls that it should have access to. But how does the auth server know what MS1 should have access to? My guess here is that this is indeed an authentication server, and that the server is meant to know ahead of time who MS1 is and what kind of access it should have, and that this is what is meant by a super trustworthy client, but I'd like to confirm if this is correct.

[@federicoestape4111]

Hi there, thanks for your amazing tutorials, they are very helpful! One question, in the first OAuth flow (the one with the authorization token in the middle) once the client gets his access token, is it short-lived as well as OAuth flow 2? or does it last longer? or forever? thanks again! Cheers! Federico from Argentina :)

[@ALEEMKHAWAR1]

very well explained.

[@sciab3674]

thanks brother, good tutorial

[@vaibhavsharma7055]

Thanks Kaushik for such a wonderful video very clearly explained like you always do. I just wanted to know why implicit flow is less secured?? although in both kind of flows(authorization and implicit flow) client application has access token which can be used to access the protected resource from resource server.

[@aarontian5979]

awesome tutorial

[@SameeraSenarathna]

Great Stuff. Thank you

[@yasharrahvar5923]

Thank you for this. What is the best way to store the access token, refresh token, ... in your node layer for later to use? How to know if the user is still logged in so we don't ask them for credentials if they close the browser?

[@juliusarieskannehjr2172]

Very nice introduction sir. I love your teachings. It helps me so much in understanding complex concepts which seems very difficult to me before. Sir, as honest request, can you please teach the implementation (demo) on the three flows you mentioned in this tutorial. Please sir👏 And thanks so much for these lessons.

[@DANIELMADHURE]

I think this is one of the best explanations so far. Is there a similar video on SAML and OIDC flow on your channel?

[@niteshshetty6873]

Thanks. It was Brilliant

[@senburbensgaming]

Thanks for the tutorial. Please make another one on OpenID Connect protocol.

[@nishant07kumar]

it will be great if you start a series on SOLID and Design Pattern in Java/any oops language. I know there are lots of material out there on internet related to these but I believe your way of teaching style will help out lots of ppl. and if you do please try to make each SOLID principle example not related to each topic. Thanks

[@sumitdas-kr6fe]

great explanation

[@JeremiBenquar1995]

Finally found an Indian that makes sense :) Thank you! Subscribed.

[@maverickmaverick5]

Loved watching it! Can you create a single flow chart showing all the flows in one frame ? for non-implicit and implicit flows ?

[@lts8683]

Thanks very much 🥰. Please make others vedio about spring boot very very very advanced
