7 Things You Should Never Share with ChatGPT

ChatGPT has become a go-to for everything, from mental health advice to speeding up work to boost productivity.

But just like anything posted online, what you share with ChatGPT will linger. Its “elephant memory” doesn’t forget easily.

And here’s the unsettling part: Your conversations with ChatGPT aren’t guaranteed to stay private. Some users have discovered other people’s chat histories due to technical glitches, which reveals major security flaws in AI interactions. Think of these AI chats as public spaces - if you wouldn’t say something in a crowded room, you shouldn’t share it with ChatGPT.

These AI chatbots serve millions of users daily, yet serious privacy risks lurk beneath the surface. The recent OpenAI vs. NYT  judgement has further directed OpenAI to store data indefinitely, bringing forth a slew of data privacy concerns within the AI community.

But this isn’t new to the tech giant, OpenAI has been facing penalties, lawsuits and controversy about its data storing practices for a while now. Between June 2022 and May 2023, over 100,000 stolen ChatGPT account credentials were found on dark web marketplaces. Even major companies like Samsung took action, banning employee use after sensitive internal code was leaked via the platform. Moreover, countless ChatGPT breaches and incidents have been recorded over a mere span of two years.

So what can you do? Start by knowing what not to share.

Here are seven types of sensitive information you should never reveal to ChatGPT and why keeping them private can shield you from data breaches, identity theft, and financial fraud.

1. Sensitive Company Information

Companies put themselves at risk when employees share private information with AI tools.The risks of Shadow AI have elevated and a worrying 77% of organizations are exploring and using artificial intelligence tools actively. While 58% of these companies have already dealt with AI-related security breaches. This raises a key question: does ChatGPT store your data after you give it access? It does, for a minimum of 30 days.

What is sensitive company information?

Sensitive company information entails any data that, if disclosed, could damage an organization. This sensitive data could harm the market position of the firm as well as its reputation and security. Here’s what it encompasses:

• Intellectual property and trade secrets

• Financial information and predictive analytics

• Databases and customer information

• Strategic plans and acquisition targets

• Proprietary software code and algorithms

• Internal presentations and policies

A mere 10 percent of firms have established dedicated AI policies aimed at safeguarding their sensitive data.

Best Practices for employees:

1. Be careful with the data you input in ChatGPT, a good measure is to ask yourself: if this data leaks, will the company be in trouble or worse, is this worth getting fired for?

2. Use a security layer that automatically detects and sanitizes your prompts without affecting productivity. See how.

3. Educate yourself with the risks of sensitive data leaks.

4. Anonymize sensitive data before it interacts with ChatGPT

5. Follow enterprise and industry protocols without indulging in ShadowAI practices

Best Practices for security teams/CISOs/leaders:

1. Provide secure alternatives to your teams to curb Shadow AI risks

2. Educate your teams with the value of proprietary data and instill a sense of collective responsibility

3. Equip yourself with advanced DLP over traditional DLP to stay AI-ready

4. Monitor activity and choose alternatives with less false positives and negatives

5. Do not use tools such as ChatGPT Enterprise and Copilot for mission critical workflows, choose tools that can be used in isolation and are not at the center of your team’s workflows.

2. Personal Identifiable Information (PII)

Your personal data serves as currency in today’s digital world, and AI chatbots have become unexpected collectors of this information. A 2024 EU audit brought to light that 63% of ChatGPT user data contained personally identifiable information (PII), while only 22% of users knew they could opt out of data collection.

What counts as personal identifiable information

Personal identifiable information (PII) covers any details that can identify you directly or combined with other data. Government agencies define PII as “information that can be used to distinguish or trace an individual’s identity, either alone or when combined with other information”.

PII falls into two main categories:

• Direct identifiers: Unique information that immediately identifies you, including:

  • Social security numbers

  • Driver’s license numbers

  • Passport information

  • Biometric data (fingerprints, retinal scans)

  • Account credentials

  • Full name (in some contexts)

• Indirect identifiers: Information that can identify you when combined with other data:

  • Date of birth

  • ZIP code

  • Gender

  • Race/ethnicity

  • Phone numbers

  • Email addresses

  • IP addresses

Research shows that 87% of US citizens can be identified just by their gender, ZIP code, and date of birth. Best practices include using sanitization tools or redaction tools that autodetect PII, replace them smartly so your data is never exposed, while rehydrating the responses with your original data - so neither is your data exposed nor do you ever have to compromise on productivity.

3. Financial and Banking Details

Financial information is among your most sensitive data, recent evaluations indicate more than one-third of finance-related prompts to ChatGPT return incorrect or partial information. This underscores the dangers of entrusting financial decisions to AI that lacks institutional-grade encryption.

What financial data you should never share

ChatGPT should never have access to your banking details. You must keep this sensitive financial information private:

• Credit card numbers and CVV codes

• Bank account numbers and routing information

• Investment account credentials

• Social Security numbers/national IDs

• Income details and tax information

• Loan application data

• Online banking passwords

Yes, it is crucial to keep any financial identifier private that could enable unauthorized transactions. ChatGPT might seem like a handy tool for financial questions, but it lacks the banking-grade encryption needed to protect your data.

Note that ChatGPT doesn’t have current information about interest rates, market conditions, or financial regulations. Financial experts warn that seeking AI advice on financial matters is “quite dangerous” because of these limitations.

Best Practices:

1. Anonymize all personal details when seeking specific advice. Remove identifying information from your financial questions.

2. Verify information independently through reliable sources. AI chatbots have helped 47% of people with financial advice, but experts found 35% of AI responses to financial queries were wrong.

3. Never request generation of official financial documents through ChatGPT, as these often need sensitive inputs.

4. Use a security layer that automates detection and masks sensitive financial data intelligently.

4. Passwords and Login Credentials

Password security is the life-blood of digital protection. Users put their credentials at risk through AI chatbots without realizing it.

Why ChatGPT should never store your passwords

ChatGPT creates serious security risks if you store passwords in it. Your passwords stay in OpenAI’s database, possibly forever. This puts your credentials on servers you can’t control.

ChatGPT lacks basic security features that protect passwords on other platforms.

OpenAI confirmed that user accounts were compromised by a malicious actor who got unauthorized access through stolen credentials. The platform still needs vital protection measures like two-factor authentication and login monitoring.

OpenAI’s employees and service providers review conversations to improve their systems. This means your passwords could be seen by unknown individuals who check chat logs.

Risks of password exposure in AI systems

Password exposure through ChatGPT leads to major risks:

• Data breaches affect entire systems: A compromised password puts all accounts with similar passwords at risk. A threat actor claimed to get credentials for 20 million OpenAI accounts in February 2025.

• AI accelerates password cracking: Modern AI password crackers break 51% of common passwords in just one minute. This makes exposed passwords through ChatGPT more vulnerable by a lot.

• Credential stuffing attacks increase: Hackers try leaked passwords on multiple sites since people reuse credentials. Research shows that one in every 7 passwords has been exposed in data breaches.

Is ChatGPT safe to use for password generation?

ChatGPT should never generate passwords. Its password generation has basic flaws that put security at risk:

1. It creates weak passwords with predictable patterns or words like “password” and “security”.

2. Similar prompts often lead to similar passwords for different users, which increases vulnerability.

3. OpenAI’s systems keep everything you type, including password generation requests.

4. The platform creates text based on patterns instead of true randomness, making passwords predictable.

Alternatives: Use a password manager

Password managers provide better security for your credentials. These tools:

• Create random, unique passwords for each account

• Keep credentials in encrypted vaults that only you can access with your master password

• Fill passwords on websites and apps automatically

• Alert you about compromised accounts in data breaches

• Find weak or reused passwords in your accounts

Password managers solve a basic problem: people have about 250 password-protected accounts. No one can create and remember strong, unique passwords for so many accounts without help from technology.

Quality password managers offer secure password sharing, encrypted vault export, and advanced multi-factor authentication. Many support passkeys too, which might replace traditional passwords in the future.

5. Creative Works and Intellectual Property

Creators who share their original work with AI tools face unique risks beyond personal data concerns. The risks are real, nearly nine in ten artists fear their creations are being scraped by AI systems for training, often without clear permission or compensation.

What is considered intellectual property

Intellectual property (IP) means creations that come from the human mind and have legal protection. Here are the main types:

• Copyrights protect original literary, artistic, and creative works including books, music, paintings, and software

• Patents safeguard inventions and technical innovations

• Trademarks protect brand identifiers like logos and names

• Trade secrets cover confidential business information that gives competitive advantage

IP rights let creators control their works and earn money from them. All the same, these protections face new challenges in the AI era, especially when courts keep saying that “human authorship is a bedrock requirement of copyright.”

How ChatGPT may use your creative content

OpenAI’s terms state they give you “all its rights, title and interest” in what ChatGPT creates. But there’s more to the story.

OpenAI can only give you rights it actually has. The system might create content similar to existing copyrighted works, rights OpenAI never had in the first place.

Your inputs could end up in storage to train future versions of the model. This means parts of your novel, code, or artistic ideas might become part of ChatGPT’s knowledge.

Many users might get similar outputs, which makes ownership claims tricky. OpenAI admits that “many users may receive identical or similar outputs.”

Legal implications of sharing IP with AI

The legal rules around AI-generated content aren’t clear yet. The U.S. Copyright Office says AI-created works without real human input probably can’t get copyright protection. Courts have made it clear that “works created without human authorship are ineligible for copyright protection.”

Just telling AI to create something, no matter how complex your instructions, usually doesn’t count as human authorship. Copyright protection might only apply when humans really shape, arrange, or change what AI creates.

Tips to protect your original work

Here’s how to protect your intellectual property when using AI tools:

1. Keep unpublished works private, particularly ones you plan to sell

2. Add watermarks or change creative content before sharing examples

3. Keep records of your creative process to show human authorship

4. Read terms of service to understand how companies might use your data

5. Look for AI platforms that offer better IP protection

6. Private Conversations and Secrets

ChatGPT’s friendly conversational style makes users reveal more than they mean to. People treat AI chatbots as digital confessionals. They share personal stories, relationship details, and private thoughts without thinking over the potential risks. ChatGPT knows how to simulate understanding so well that it creates a false sense of confidentiality.

Why you should avoid oversharing with ChatGPT

ChatGPT poses the most important privacy risks when users share too much. Human conversations fade from memory, but everything you type into ChatGPT stays stored on external servers. OpenAI employees, contractors, or hackers during security breaches might access these conversations. A ChatGPT bug in March 2023 let some users see titles of other users’ conversation history. This showed how vulnerable the system could be.

Can ChatGPT remember your chats?

ChatGPT has reliable memory capabilities. OpenAI upgraded ChatGPT’s memory features to include “reference all your past conversations”. The system can recall details from previous chats even without being told to remember them. ChatGPT stores information through manually saved memories and learns from your chat history.

7. Illegal or Harmful Requests

Sharing sensitive information or making harmful requests to ChatGPT raises serious ethical and legal issues. OpenAI keeps improving its safeguards against misuse, but cybercriminals keep trying new ways to get around these protections.

Examples of illegal or unethical prompts

ChatGPT users make harmful requests that usually fit these categories:

• Dangerous content generation: Instructions to create weapons, explosives, or harmful substances

• Illegal activities: Help with fraud, hacking, or other criminal acts

• Explicit content: Attempts to create inappropriate or exploitative material

• Misinformation spreading: Requests to create false information or propaganda

• Identity impersonation: Requests to copy specific people without permission

Cybercriminals have created special “jailbreak prompts” to bypass ChatGPT’s safety features. These include prompts like DAN (Do Anything Now), Development Mode, and AIM (Always Intelligent and Machiavellian) that trick the AI into creating restricted content.

Does ChatGPT take your information?

ChatGPT actively collects and stores your data. OpenAI’s privacy policy states that the company collects two types of personal information:

1. Automatically received data:

   • Device information (device type, operating system)

   • Usage data (location, time, version used)

   • Log data (IP address, browser used)

2. User-provided data:

   • Account information (name, email, contact details)

   • User content (all prompts, questions, and uploaded files)

OpenAI uses this data to train its models, which means your conversations help develop future ChatGPT versions. The company states they don’t use your data for marketing or sell it to third parties without consent. However, their employees and some service providers can review your conversations.
