Integrating ChatGPT for Single Sign-On (SSO) in mobile apps presents significant, almost insurmountable, challenges primarily due to its nature as a large language model, not an authentication system. Key hurdles include profound security risks, as ChatGPT is not designed to securely manage or verify sensitive user credentials and lacks the rigorous auditing capabilities essential for identity providers. Furthermore, there's a fundamental protocol mismatch; SSO relies on established standards like OAuth 2.0 or OpenID Connect, which ChatGPT does not natively support or implement. Data privacy and compliance become critical concerns, as feeding sensitive personal identifiable information (PII) to a third-party AI for authentication purposes raises serious regulatory and trust issues. Reliability and performance are also major obstacles; ChatGPT's responses can be non-deterministic and its API is not engineered for the low-latency, high-availability demands of a core authentication service. Ultimately, using ChatGPT directly for SSO integration would introduce unacceptable vulnerabilities and functional limitations, making it an unsuitable and potentially dangerous choice for securing mobile application access.
