What is the difference between OAuth 2.0 and Auth0? Which one should I use to develop the authentication system?
OAuth 2.0 is a standardized authorization protocol, Auth0 is a company that sells an identity management platform with authentication and authorization services that implements the OAuth2 protocol (among others).
OAuth 2.0 is a protocol that allows a user to grant limited access to their resources on one site, to another site, without having to expose their credentials.
Auth0 is an organisation, who manages Universal Identity Platform for web, mobile and IoT can handle any of them — B2C, B2B, B2E, or a combination.

In case if you cannot understand any of above,
OAuth 2 - is a standard or protocol to implement authorization for any kind of software (windows, mobile or web)
Auth0 - is a software product (cloud and on-prem), that implements the OAuth2 protocol. You can use Auth0 to simplify your
authentication and authorization requirements.
We mainly use auth 2.0 for session based security management at server side. OAuth 2.0 is an authorisation framework that enables a third-party application to obtain limited access to resources the end-user owns. It is about resource access and sharing. While https://auth0.com is a company that sells an identity management platform for authentication related task. So with the help of auth0.com services an app developer don't need to write code for login/registration/social login and its not needed to think about its security. Complete user management task manages by auth0 organisation.
What Identity Provider are you aiming to use?
Auth0, identityserver, ADFS 4.0 etc. all support the OAuth stack.
Using implicit OAuth flow you can connect your Angular application to any of these.

I have created a Web API using .net core 5. I have secured the app using the Microsoft Identity platform. Clients app are able to get to the resource based on their scope/role. So I know that my api is secure.
Now, I need to add the API to Azure API Management tool.
So my question is should I enable OAuth from the Azure API Management to secure my web api even though my app is already secured?. What would be the reason that I enable OAuth from API management?
APIM is a proxy to the backend APIs and implementing security mechanisms to give an extra layer of security to prevent unauthorized access to APIs is a recommended practice.
Configuring OAuth 2.0 Server in APIM merely enables the Developer Portal’s test console as APIM’s client to acquire a token from Azure Active Directory. In the real world, customer will have a different client app that will need to be configured in AAD to get a valid OAuth token that APIM can validate.
OAuth is an authorization framework which allows a recognized client to acquire an access token from an authorization server.
As given in this Microsoft Doc, the Microsoft Identity Platform uses the OAuth 2.0 protocol for handling authorization.

I'm new to OAuth 2.0 and OpenIDConnect
I want to ask if is it necessary to implement OAuth 2.0 and OpenIDConnect for our login, register flow of our own created client application (mobile apps and server side app)?
Because I've been searching tutorial to implement login, register flow the best practice right now is using OAuth 2.0 and OpenIDConnect but their implementation is toward to securing our API against other people client application. Is this auth flow is just used to secure another people client application to access our API?
Thank you
OAuth 2.0 is both elegantly simple or extremely complex depending on your understanding of the technology and how to implement authorization.

No, it is not necessary to implement. There are many methods of authentication and authorization. OAuth is just one of the more popular methods.
A simpler and terrible method is to just implement username and passwords for your users. Simpler, in this case, is a relative term as now you need to worry about keeping usernames and passwords stored somewhere securely.
OAuth can be used to secure public access to your website, applications (REST endpoints), and more. OAuth can be used for server to server authorization. In the end, OAuth is just a method of creating a token that is presented to a service. The service verifies the access rights of that token and denies or proceeds with the request.
Authorization and Authentication are domains that require a lot of experience to implement correctly. There are many nuances to consider. That is why so many companies are breached, they do it wrong or implement weak methods. At one company I visited for an audit, I wrote down 10 usernames and passwords because everyone had yellow postit notes on their monitors. Even the best OAuth implementation will have problems with that level of security.
We have an existing MVC angular application enabled with ADFS WS-Fed authentication. The application has many API's hosted as a part of the solution which is internally accessed by views. Now, We have a requirement for the API to be published to other developers.
I am thinking of enabling OAuth/OpenId for the endpoints and enable other developers to access. I need your inputs regarding my approach.
There is no support in ADFS 2.0 for OpenID Connect and OAuth.
The only API option you have is via WCF.
I am constantly get confused by OpenID Connect and Oauth2, and I read this article and get a sense that Google is using OpenID Connect https://auth0.com/docs/oauth-web-protocol (but I remember google used Oauth2 as providing auth service to 3rd parties), see the following quote
Auth0 supports the OpenID Connect / OAuth2 Login protocol. This is the protocol used by companies like Google, Facebook and Microsoft among others so there are plenty of libraries implementing it on various platforms.
Moreover, the above URL seems to say Auth0 is using OpenID (rather Oauth)? See the following quote:
GET https://YOUR_NAMESPACE/authorize/?
response_type=code
&client_id=YOUR_CLIENT_ID
&redirect_uri=http://YOUR_APP/callback
&state=VALUE_THAT_SURVIVES_REDIRECTS
&scope=openid
http://openid.net/specs/openid-connect-basic-1_0.html
OpenID Connect is basically authentication built on top of OAuth 2.0.
OAuth 2.0 by itself didn't standardise authentication (just authorization) and the confusion you have likely comes from the fact that each of the companies that are now switching to OIDC previously had already poured their own "authentication sauce" on over their OAuth 2.0 implementations. In practice this meant that each had their own set of scopes and their own version of what is a standard /userinfo endpoint in OIDC, but the authorization mechanism in all cases (including OIDC) is based on OAuth 2.0.
To wrap up by answering your question: Yes, both of the endpoints you mention support OpenID Connect.
We want to secure our api using OAuth.
Our server exposes functionalities through APIs. Separate UI applications consume these APIs.
Users use these UI application to access their resources. Since there are only two systems (client and server) involved,
we would like to have 2 legged authorization flow instead of 3legged with redirections. Also we would like have
separate UI (client) application verification once and use this verification code to perform user login and get access token.
Currently we are evaluating spring security framework. Most of spring security tutorials/article talks about 3-legged oAuth with bearer token approach.
I’m not sure if it supports request singing and above mentioned required process. Is there any other open source framework we can use?
