OAuthpohjainen

OAuthpohjainen refers to a system or service that utilizes the OAuth protocol for authorization. OAuth, which stands for Open Authorization, is an open standard for access delegation, commonly used as a way for internet users to grant websites or applications access to their information on other websites but without giving them the passwords. Instead, OAuth provides clients with a user-approved "token" that grants access to specific resources for a limited time.

When something is described as OAuthpohjainen, it means it relies on this framework to manage permissions and access. For example, an OAuthpohjainen application might allow you to log in using your Google or Facebook account. In this scenario, the application is not requesting your Google or Facebook password directly. Instead, it uses OAuth to ask for your permission to access certain information from your Google or Facebook profile, such as your name or email address. You are then redirected to Google or Facebook to approve this request. Upon approval, a token is issued to the application, granting it the specified level of access.

This approach enhances security by not sharing user credentials and provides users with more control over what data third-party applications can access. It is a widely adopted standard in modern web and mobile application development.
