# Overview
OAuth enables AppSumo Partners to utilize our new licensing service.
# How it works
The AppSumo licensing service relies on Open Authorization (OAuth) to give the new customer access to your application. A customer can access your product via their products page on AppSumo. After allowing access to your product, they are redirected to your application. Using a series of tokens, you can validate the license the user has purchased and allow them access.
# OAuth
OAuth (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. This mechanism is used by companies such as Amazon, Google, Facebook, and others to permit the users to share information about their accounts with third-party applications or websites.
