Oath 2.0 flow , how it's working

Question

Accepted Answer

OAuth 2.0 is a protocol for authorization, allowing third-party applications to access user data without sharing passwords.

OAuth 2.0 involves four roles: resource owner, client, authorization server, and resource server.
The flow starts with the client requesting authorization from the resource owner.
The resource owner grants authorization and provides the client with an authorization grant.
The client then requests an access token from the authorization server using the authorization grant.
The authorization server authenticates the client and authorization grant, then issues an access token.
The client uses the access token to access protected resources on the resource server.
OAuth 2.0 supports several grant types, including authorization code, implicit, client credentials, and resource owner password credentials.
OAuth 2.0 also includes refresh tokens, which allow clients to obtain new access tokens without requiring the user to re-authenticate.
