Answer from AI
OAuth 2.0 is an authorization protocol that allows third-party applications to obtain limited access to a user's resources without sharing their password.
Main steps of OAuth 2.0 authorization:
-
Authorization Request: The client (application) redirects the user to the authorization server with a request for access to certain resources.
-
User Authentication: The user enters their credentials on the authorization server.
-
Authorization Code: If the user agrees, the authorization server returns a temporary code to the client.
-
Exchange Code for Access Token: The client sends the code to the authorization server to obtain an access token.
-
Access Resources: The client uses the access token to make requests to protected resources on the resource server.
-
Token Refresh (optional): If needed, the client can obtain a new token using a refresh token.
Example of a simplified authorization request:
GET /authorize?response_type=code&client_id=CLIENT_ID&redirect_uri=REDIRECT_URI&scope=read_profile HTTP/1.1
Host: authorization-server.com
Thus, OAuth 2.0 provides a secure and standardized way to delegate access without sharing passwords.
