The Importance of Phone Numbers and Privacy in ChatGPT AI Technology.

ChatGPT requires a phone number for two-factor authentication to ensure that the user is a real person and their account is not easily hacked. The phone number is only used for security reasons and OpenAI promises not to use personal information for other purposes. Unfortunately, ChatGPT does not accept VoIP numbers, and users need an active mobile number to verify their account. The service has been banned in Italy due to privacy concerns related to how the large language model was trained, which involves the collection of massive amounts of data.
