What is OAuth RFC?
The OAuth 2.0 Core Framework (RFC 6749) defines roles and a base level of functionality, but leaves a lot of implementation details unspecified. Since the publication of the RFC, the OAuth Working Group has published many additional specs built on top of this framework to fill in the missing pieces.
Which OAuth grant type should I use?
For most cases, we recommend using the Authorization Code Flow with PKCE because the Access Token is not exposed on the client side, and this flow can return Refresh Tokens. To learn more about how this flow works and how to implement it, see Authorization Code Flow with Proof Key for Code Exchange (PKCE).
What is the OAuth 2.0 implicit grant type?
The Implicit Grant Type is a way for a single-page JavaScript app to get an access token without an intermediate code exchange step.
What is auth code grant type?
The Authorization Code grant type is used by confidential and public clients to exchange an authorization code for an access token. After the user returns to the client via the redirect URL, the application will get the authorization code from the URL and use it to request an access token.

What is OAuth azure2?
The OAuth 2.0 is the industry protocol for authorization. It allows a user to grant limited access to its protected resources. Designed to work specifically with Hypertext Transfer Protocol (HTTP), OAuth separates the role of the client from the resource owner.
Which OAuth grant type refresh token?
The Refresh Token grant type is used by clients to exchange a refresh token for an access token when the access token has expired. You can get refresh tokens only for the OAuth 2.0: Authorization code flow. New OAuth2 access tokens have expirations.
What is OAuth client credentials grant?
The OAuth 2.0 client credentials grant flow permits a web service (confidential client) to use its own credentials, instead of impersonating a user, to authenticate when calling another web service.
Is OAuth2 token JWT?
JWT and OAuth2 are entirely different and serve different purposes, but they are compatible and can be used together. The OAuth2 protocol does not specify the format of the tokens, therefore JWTs can be incorporated into the usage of OAuth2.

What is client credentials grant type?
The Client Credentials grant type is used by clients to obtain an access token outside of the context of a user. This is typically used by clients to access resources about themselves rather than to access a user’s resources. Client Credentials (oauth.com)
What is refresh token grant type?
The Refresh Token grant type is used by clients to exchange a refresh token for an access token when the access token has expired. This allows clients to continue to have a valid access token without further interaction with the user.
Which is better OAuth or JWT?
OAuth2 is very flexible. JWT implementation is very easy and does not take long to implement. If your application needs this sort of flexibility, you should go with OAuth2. But if you don’t need this use-case scenario, implementing OAuth2 is a waste of time.
What are the different OAuth grant types?
OAuth Grant Types 1 Authorization Code 2 PKCE 3 Client Credentials 4 Device Code 5 Refresh Token More
How does an OAuth grant work?
For any OAuth grant type, the client application has to specify which data it wants to access and what kind of operations it wants to perform. It does this using the scope parameter of the authorization request it sends to the OAuth service.
What is OAuth access token types registry?
