A Practical Guide to Protecting Your Account, Data, and Privacy with OpenAI's ChatGPT
Updated: Aug 13
Navigating the online world can be daunting, especially when it comes to protecting your personal information. This guide is designed to help you secure your account, safeguard your data, and maintain your privacy while using OpenAI's ChatGPT. Let’s dive in!
1. Lock Down Your Account
Use a unique, strong password. If your account supports it, consider signing in with a passkey. You can find this option under Settings → Security → Passkeys. Passkeys allow you to sign in without a password using Face ID, Touch ID, or a security key. For more details, check the OpenAI Help Center's guide on Passkeys to secure your OpenAI account.
Turn on multi-factor authentication (MFA). Go to Settings → Security → Multi-factor authentication. You can choose from options like an authenticator app, push notifications, or SMS/WhatsApp codes. The available methods may vary based on your device, country, and account type. For more information, refer to the OpenAI Help Center's article on Enabling or disabling multi-factor authentication (MFA).
Consider Advanced Account Security if you are a higher-risk user, such as a journalist or public figure. This opt-in mode disables weaker methods like email and SMS codes. Instead, it requires phishing-resistant options like passkeys or a physical security key, along with a recovery key that you must save.
If you suspect someone else has access to your account, reset your password first. After that, enable MFA. Just enabling MFA alone won’t log out existing sessions.
2. Control What Your Data Is Used For
"Improve the model for everyone" is the master training toggle. You can find it in Settings → Data Controls. When this option is on, your chats and saved memories may be used to help train future models. If you turn it off, new conversations will no longer be used for training. For more information, check OpenAI's article on How ChatGPT learns about the world while protecting privacy.
Turning training off doesn’t delete your history. Your conversations will still appear in your chat history, but they won’t be used for training.
Temporary Chat is a great feature. It doesn’t appear in your history, doesn’t create memories, and isn’t used for training at all. This is perfect for one-off sensitive questions. However, keep in mind that OpenAI retains these chats for up to 30 days for safety purposes before deletion.
Business, Enterprise, and Edu accounts are not trained on by default, regardless of the consumer toggle.
3. Manage Memory Carefully
ChatGPT can remember facts about you across chats to personalize responses. Here’s how to manage that memory:
Review and delete what it remembers. Go to Settings → Personalization → Manage memories.
Turn off "Reference saved memories." This stops ChatGPT from using stored facts about you and also disables referencing your past chat history.
Even after you delete a memory, OpenAI notes that deleted content may briefly persist in backend logs for safety and debugging purposes before full removal.
If you connect Google or other third-party apps, review what’s synced. Connected-app content follows separate rules from typed chat content. For more details, see OpenAI's data-controls FAQ for whichever integration you use.
4. Clean Up Your History and Links
Delete individual chats or bulk-delete them from Data Controls.
Archive chats that you want to keep but don’t need in your main list.
Shared links: If you’ve ever generated a public or view-only link to a conversation, go to Data Controls → Shared links to review and revoke any links you no longer want active.
5. Know What Not to Share
Regardless of your settings, some things should never go into any AI chat:
Passwords, API keys, or authentication tokens
Full financial account numbers or national ID numbers
Confidential employer or client data that you’re not authorized to share externally
Sensitive medical or legal details tied to identifiable people
If your employer provides ChatGPT (Business/Enterprise), check their policy. Even with strong personal privacy settings, workspace admins can typically see more than you might expect on managed accounts.
6. Treat Output as a Draft, Not a Verdict
ChatGPT can be wrong, especially on niche facts, citations, math, or fast-changing information. Always verify anything important—medical, legal, or financial—before acting on it. Be cautious about following instructions to install software or run code without fully understanding what it does first.
7. Watch for Prompt Injection
If you use ChatGPT Atlas, browsing, or connected apps (like Google Drive or Gmail), be aware of prompt injection. Malicious content on a webpage or in a document can attempt to hijack an AI agent's instructions. Always review what actions an agent is about to take, especially anything that sends messages, makes purchases, or modifies files, before approving it.
