6 Reasons Not to Share ChatGPT, Gemini, Claude Accounts
The article explains six risks of sharing paid chatbot accounts for ChatGPT (OpenAI), Gemini (Google) and Claude (Anthropic). It warns that sharing login credentials exposes email/passwords and linked services, reveals prompt/history content, reduces personalization of AI responses, and can create legal or policy liability because account-sharing typically violates providers' terms and can lead to account termination. The piece cites reporting in the Wall Street Journal and user anecdotes (Connor Effrain, Olivia Martin, Xavier Wisniewski). It also notes that plugin integrations (e.g., Gmail, Google Calendar, Teams, Apple Music, Indeed, LinkedIn, Stripe) and new agentic commerce features such as “Instant Checkout” increase the risks of exposing sensitive or financial data. The article recommends using single-user accounts or local AI tools as safer alternatives.
Highlights user privacy, security and policy risks from sharing accounts for major LLM-based chat services and shows how integrations (plugins, commerce features) can expose sensitive data — relevant to platform trust and downstream integrations but not industry-shifting.

Six Sensitive Data Types to Never Share with Chatbots
This German article warns users against entering sensitive personal or corporate information into AI chatbots such as ChatGPT. It lists six taboo categories: personal contact details (name, address, phone), identity documents (passport, ID), passwords and login credentials, financial documents and account numbers, medical and health records, confidential company information, and requests hinting at illegal activity. The piece explains that chatbot inputs can be used to train models, may be stored indefinitely, and can be exposed through breaches or misuse, citing a prior incident where ChatGPT allegedly revealed other users' passwords. It recommends anonymizing data for medical queries, avoiding uploads of official documents, and training employees before deploying tools like Microsoft Copilot. The article was republished on 2026-04-17 (originally published 2025-04-16).
How to Check if Your AI Accounts Were Hacked
TechCrunch published a guide explaining how users can determine whether their accounts on popular conversational AI services — ChatGPT, Claude, and Perplexity — have been compromised. The article recommends standard security practices (unique passwords, password managers, and multi-factor authentication) and details how each platform exposes or hides active sessions and how to sign out or reset access. It notes that ChatGPT and Perplexity support MFA and explicit session views, while Anthropic’s Claude relies on email login links and does not use passwords or MFA.
Actions That Can Get You Banned From ChatGPT
The article explains that ChatGPT subscriptions are strictly personal and outlines behaviours likely to violate OpenAI's terms of service. Prohibited uses include sharing credentials (account pooling/rotation), running unattended automation or CI on a subscription, serving other users or agents, and embedding subscription-authenticated calls inside commercial products or reselling access. The author recommends moving non-personal or production usage to per-token (pay-as-you-go) API plans. The piece also references broader platform behaviour (Anthropic tightening subscriptions) and mentions Manifest as a service that routes requests between subscriptions and API keys to keep personal and paid usage separate.
