Using this information: While OAuth is primarily designed to facilitate authorization, misusing it for authentication can lead to significant security implications. Utilizing OAuth for authentication rather than its intended purpose can result in various vulnerabilities that threaten both user data and application integrity. For instance, when OAuth is improperly implemented to handle user authentication, applications may incorrectly request extensive permissions, allowing access to sensitive user information beyond what is necessary. This excessive access not only increases the risk of data exposure but can also make users vulnerable to phishing attacks; users might be tricked into granting permissions to malicious applications that appear legitimate. Moreover, the lack of robust authentication controls when relying on OAuth can lead to ineffective identity verification, enabling unauthorized access to user accounts.
