How to implement secure login authorization through a browser?

Many Word plug-ins provide convenient browser login authorization function: click the plug-in login button, and the default browser will be automatically opened and jumped to the plug-in official website for login and authorization. After the authorization is successful, the Word plug-in can access user data. How is this cross-application authorization mechanism implemented?

Let’s take a practical case as an example: click the plug-in login button, open the browser and jump to the plug-in official website. If the user has logged into the official website, he or she will directly enter the authorization page; otherwise, she or she will need to log in to the official website first and then enter the authorization page. After the authorization is completed, the Word plug-in will complete the login.

The key is to understand: Word plug-in cannot directly obtain callback information from the browser, and the two are independent applications. This authorization method is similar to "Scan the QR code to log in on your mobile phone":

Word plugin login	Scan the QR code to log in
Word plug-in jumps to the browser, no callback information	Scan the QR code on your phone, and there is no callback for independent applications
Word plug-in and browser are independent applications	Mobile phone applications and computer applications are independent applications

Both face the challenge of cross-application communication. Word plug-in is authorized through browser login, cleverly taking advantage of the browser's independence and user operations. Users complete login and authorization in the browser, without the need for Word plug-ins to interact with the browser, thereby bypassing the communication restrictions between applications and achieving safe and reliable cross-application authorization. This mechanism ensures security because sensitive information interactions are carried out on the browser side, and the Word plug-in itself does not need to process sensitive information.
