Don’t tell your AI chatbot these 5 things if you want to keep your money safe

Chatbots like ChatGPT, Gemini, Copilot, and Claude have become go‑to tools for quick answers—including financial questions. But treating them like a private financial advisor can backfire. A Washington Post column recently highlighted specific types of information you should never share with an AI chatbot. Here’s what to avoid and why.

What happened

The Washington Post’s personal finance column ran a piece titled “Don’t tell your AI chatbot these 5 things to keep your money safe.” It draws on growing awareness that chatbot conversations are often stored, may be used for model training, and can be accessed by hackers if your account is compromised. Even if a chatbot promises not to store data, leaks and breaches have shown that no platform is completely immune. The column is one of several recent articles (including coverage by BBC and NerdWallet) that underscore the privacy risks of sharing personally identifiable information (PII) with AI tools.

Why it matters

Chatbots are not designed to be secure vaults for sensitive data. When you type your full bank account number, Social Security number, or answers to security questions, that information may be retained on company servers. OpenAI, Google, and other providers have acknowledged that prompts containing PII carry privacy risks. If your account is hacked—or if the company suffers a data breach—that information could be used to drain accounts, apply for credit in your name, or answer security questions on other platforms. The convenience of asking a bot for budgeting advice is real, but the cost of oversharing can be much higher.

What readers can do

Protecting your money doesn’t mean you have to stop using chatbots. It just means drawing a clear line between general advice and personal data. Here are five categories of information to keep out of your chat history.

1. Bank account and credit card numbers

Never paste your full account number, routing number, or credit card digits into a chatbot. Even if the bot claims to help you categorize spending or find a transaction, it can’t actually access your bank. For that kind of task, use your bank’s official app or website. Instead of sharing numbers, ask generic questions like “What are common fees for checking accounts?” or “How do I dispute a credit card charge?”

2. Login passwords and two‑factor codes

Your chatbot doesn’t need your password to help you—and storing passwords in chat logs is a huge risk if your account is ever compromised. The same goes for two‑factor authentication (2FA) codes. A recent BBC investigation showed how easily an attacker could extract personal data from a chatbot’s conversation history. Use a dedicated password manager instead.

3. Social Security and government ID numbers

Your Social Security number, driver’s license number, or passport number should never be typed into a chatbot, even in a private‑mode conversation. Identity thieves can use these numbers to open fraudulent accounts or file tax returns in your name. If you need help understanding Social Security benefits or renewing a license, rely on official government websites, not AI.

4. Answers to common security questions

Questions like “What is your mother’s maiden name?” or “What was the name of your first pet?” are often used to reset passwords on financial accounts. If you tell a chatbot those answers, and the chat log is later accessed, an attacker could use them to hijack your accounts. A safer approach: ask the chatbot for tips on how to create secure answers (like using a random phrase), but do not share your actual answers.

5. Personal contact and location details

Your home address, full date of birth, and phone number may seem harmless, but combined with other data they can lead to identity theft or doxxing. Scammers sometimes use information scraped from chatbot logs to craft targeted phishing messages. If you need location‑specific advice (e.g., local tax rules), ask generally: “What are typical property tax rates in my state?” without typing your zip code.

Bonus: How to safely use chatbots for financial tips

Chatbots can be helpful for learning financial concepts, comparing products, or brainstorming a budget. The key is to keep it generic. Ask questions like:

• “What should I look for in a high‑yield savings account?”
• “How do I calculate compound interest on a $10,000 investment over 10 years?”
• “What are the pros and cons of a Roth IRA?”

Never input real numbers you aren’t willing to share publicly. If a chatbot asks for personal details to “personalize” advice, treat that as a red flag. For actual transactions or account management, always go directly to your bank or financial institution’s secure portal.

Conclusion

Chatbots are tools, not confidants. A 2026 Washington Post column put it plainly: treat your chatbot conversations as if they could be read by anyone. By avoiding these five categories of financial information, you reduce the risk of account takeover, identity theft, and fraud. When in doubt, don’t share it.
