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.

    @Java Brains : One fundamental question I always think about. 
    Why would any service take the pain of maintaining the auth servers and making sure they follow the OAuth protocol ?
    Do they get paid for every such call from a client ?

    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.

    In the flow 1 in step 3 Which protocol the Authorization Server uses to send the authentication request to the Resource owner ? How does it know where the Resource owner is and how to contact him?

    Hello, Thank you for your great efforts,
    could you please cover sso with active Directory and Apache server ?

    Thanks Koushik for creating this video. Could you please explain how authorization code flow adds more security compared to Implicit flow.

    Is it like when Resource owner gives his consent, the authorization server gives authorization token back, which goes to the client and then client sends a separate request from a server which is trusted on Authorization server side(using SSL/TLS) and then only authorization server grants the access token ?

    Also, can you please create a video series on SAML and it's relation with OAuth.

    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 .

    I think authorization server sends access token to resource owner means browser and from there it redirects to client

    Hi koushik, How to maintain the user login and logoff session with mobile app and web app connected to microservices. But with JWT it looks like it depends on JWT token expiration date, but how we can can maintain a sync with user log off session.
