TMTPOST -- OpenAI is considering a new feature that would allow users to sign in to third-party apps using their ChatGPT account, according to a company web page published Tuesday. The company is currently seeking feedback from developers interested in integrating the service. With ChatGPT now drawing around 600 million monthly active users, OpenAI appears poised to leverage its growing user base to expand beyond its core chatbot functionality. The proposed "Sign in with ChatGPT" feature would put OpenAI in closer competition with tech giants like Apple, Google, and Microsoft, all of which offer similar identity services across a wide range of digital platforms. If launched, the feature could open doors for OpenAI to extend its presence into areas like e-commerce, social networking, and personal productivity tools, making ChatGPT not just a conversation tool, but a broader gateway into the digital ecosystem.
