As with other online services, hackers can target and compromise accounts on popular AI platforms such as ChatGPT, Claude, and Perplexity.
TechCrunch has created a comprehensive guide to protect yourself if you suspect someone has broken into your account on one of the internet’s most popular platforms, social networks, or messaging apps. Here’s how to tell if your account on AI Platform has been hacked.
As always, we recommend using unique passwords stored in a password manager and turning on multi-factor authentication (MFA) so that even if someone steals your password, they can’t log in without a second piece of information.
ChatGPT and Perplexity offer MFA. Claude doesn’t. Because instead of asking for a password, Anthropic’s AI chatbot will send a login link to your email address.
All three of these AI platforms offer similar ways to see if there are suspicious devices logged into your account. We’ll explain exactly how each platform works.
Chat GPT
To check if someone has broken into your ChatGPT account, open it in your computer’s browser, click on your username in the bottom left corner, go to Settings, then Security and Login, and finally click Active Sessions.
It will show you where you are logged into your ChatGPT account. If you see a device that you don’t recognize, you can log out of it. You can also click “Log out all.”

If you wish to change your password at this point, you must log out of your account.
Then, on the ChatGPT website, click “Login” in the bottom left corner, enter your email address, click “Forgot your password?” and click “Continue.”
ChatGPT will send you an email containing a 6-digit code. Enter the code on the ChatGPT login page, click Continue, and enter your new password.
You can also click “Reset Password” in the email you receive for official instructions on how to do so.
Claude
For Claude, open it in your computer’s browser, click your username in the lower left corner, then click (Settings), then (Account). Here you will see “Active Sessions”.
If you see something you don’t recognize, hover over it, click the three vertical dots that appear on the right, and click Logout or Exit.

If necessary, click Logout from all devices.
At that point, you will be able to log back into your account using your email address. You will receive an email with a link to log in. Claude does not allow passwords to be used at all, so there is no need to change them.
puzzled
In the case of Perplexity, the AI-powered search engine doesn’t show you where you’re logged in.
So, if you’re worried that someone has broken into your account, go to Perplexity in your browser, click your username in the bottom left corner, and click (All Settings). Finally, click “Sign out of all sessions” and click “Confirm”.

At this point, you can log in again by entering your email address. You will then receive an email with a unique 6-digit code. Log in by entering the code on the website or directly by clicking the “Sign in” button in your email.
