Editing Understanding OAuth 2.0: Token-Based Authorization (section)

== Security Best Practices ==

To enhance security, consider these best practices:

* '''Use PKCE (Proof Key for Code Exchange)''': Prevents code interception attacks in mobile and SPA applications.
* '''Use Short-Lived Access Tokens''': Reduces the risk of token leakage by expiring them quickly.
* '''Store Tokens Securely''': Avoid storing access tokens in local storage or exposing them in URLs.
* '''Use HTTPS''': Always ensure secure communication between clients and servers.
* '''Implement Token Revocation''': Allow users to revoke access when needed by invalidating tokens.
* '''Prefer Authorization Code Flow with PKCE''': Ensure security in client-server communication, especially for mobile and web applications.
* '''Implement Scopes and Permissions''': Limit the access granted to applications by defining specific scopes for each request.
