The “aadsts65004” error code, in the context of application authentication, signals a specific denial event. This event occurs when a user actively chooses not to grant an application the permissions it requests during the authorization process. For example, a user attempting to log in to a new application through their Microsoft account may be presented with a list of permissions the application requires. If the user selects “decline” or explicitly revokes consent for any of these permissions, the “aadsts65004” error is generated, preventing the application from accessing the user’s data.
This denial is crucial for maintaining user privacy and security. It empowers individuals to control which applications can access their personal information and to what extent. Historically, this type of granular control was not always available, leading to potential overreach by applications and raising privacy concerns. The ability to decline consent provides a mechanism for users to mitigate these risks and enforce their data rights.
