Seven Personal Data Mistakes to Avoid When Using ChatGPT

ChatGPT can feel conversational, but users should refrain from providing sensitive credentials such as passwords, PINs, or full bank card numbers, even though it can help with password creation or security concepts. When uploading files, people must remove personal identifiers like names, addresses, IDs, or signatures that may be embedded in passports, contracts, or payslips. Confidential work material—including client names, financial figures, or unpublished projects—should be vetted against company policies before being pasted into the model.

The AI is not a substitute for medical diagnosis or for making high-stakes personal choices; it can offer explanations but not definitive answers. Sharing other people's private communications or images without consent is also discouraged. Users should treat the model's responses as suggestions, double-check facts, and use source verification, especially for critical topics such as health, finance, or legal matters.
