🔑 OAuth 2.0 Overview — OAuth 2.0 is an open-standard protocol that allows applications to access user resources on another service without sharing passwords. It uses tokens to grant limited access to user accounts.
🔄 Authorization Flow — The OAuth 2.0 process involves several steps, including obtaining a client ID and secret, redirecting users to an authorization endpoint, and exchanging authorization codes for access tokens.
🔒 Security Benefits — OAuth 2.0 enhances security by allowing applications to access user accounts without revealing passwords. Tokens expire after a set period, reducing the risk of unauthorized access.
📱 Versatility — OAuth 2.0 supports various applications, including web, mobile, and IoT devices, making it a flexible solution for different platforms.
🔄 Token Management — OAuth 2.0 involves managing access and refresh tokens, which are used to maintain secure access to resources over time.
OAuth 2.0 Components
🆔 Client ID and Secret — These are credentials obtained during app registration, essential for initiating the OAuth flow.
🔗 Authorization Endpoint — The URL where users are redirected to grant permissions to the application.
🔑 Access Token — A token obtained after user authorization, used to access protected resources.
🔄 Refresh Token — A token that allows the application to obtain a new access token without user intervention.
🔒 Scopes — Define the level of access the application is requesting from the user.
Security Features
🔒 Token Expiry — Access tokens have a limited lifespan, reducing the risk of misuse if compromised.
🔐 HTTPS Requirement — All OAuth 2.0 communications must be secured using HTTPS to prevent interception.
🔄 PKCE — Proof Key for Code Exchange is used to enhance security in mobile and native applications.
🛡️ Bearer Tokens — OAuth 2.0 uses bearer tokens, which require secure transmission to prevent unauthorized access.
🔍 Granular Permissions — Users can grant specific permissions to applications, limiting access to only necessary resources.
Implementation Steps
1️⃣ Register Application — Sign up on the platform's developer portal and obtain a client ID and secret.
2️⃣ Initiate OAuth Flow — Redirect users to the authorization endpoint with the necessary parameters.
3️⃣ User Authorization — Users grant permissions, and the application receives an authorization code.
4️⃣ Exchange Code for Token — The server exchanges the authorization code for an access token.
5️⃣ Use Access Token — The application uses the access token to make authenticated requests to the resource server.
