What Personal Information Should I Never Share With ChatGPT?
Step-by-Step Guide
Never share your Social Security number or government ID numbers
Your Social Security number (SSN), Medicare ID, driver's license number, or passport number should never be typed into any chat — including ChatGPT. These numbers are the keys to your identity. ChatGPT doesn't need them to help you, and there is never a legitimate reason to share them.
Keep bank account and credit card details private
Never type full bank account numbers, routing numbers, credit card numbers, PINs, or online banking passwords into ChatGPT. If you want help understanding a bank statement or writing a message to your bank, you can describe the situation in general terms. For example: 'I see an unexpected charge on my account — help me write an email to my bank asking about it.'
Don't share passwords or security answers
Never share passwords, PINs, or answers to security questions (like 'mother's maiden name' or 'first pet's name') with ChatGPT. These are used to protect your accounts, and sharing them anywhere online — even in an AI chat — is a security risk.
Be careful with full names, addresses, and phone numbers
For most questions, ChatGPT doesn't need your full name, home address, or phone number. When asking for help with a letter, you can use placeholders: 'Write a complaint letter from [Your Name] at [Your Address]' and fill in the details yourself before sending. This gets you a great result while keeping your info private.
Use general terms for medical questions
You can absolutely ask ChatGPT about medical topics — symptoms, medications, conditions — without revealing identifying information. Instead of 'I'm Jane Smith, born 1952, and my doctor prescribed...' just say 'I'm a 70-year-old woman and my doctor prescribed X — what should I know about it?' You get the same helpful answer with no personal exposure.
What IS safe to share with ChatGPT
It's perfectly fine to share the general details of everyday situations: the text of an email you received (without sensitive account numbers), a recipe you want to modify, a travel destination, a topic you want to learn about, a piece of writing you want help editing, or general descriptions of problems you need advice on. Most everyday conversations involve zero sensitive data.
