If you’ve ever wondered whether someone else might be poking around inside your ChatGPT, Claude, or Perplexity account, you’re not being paranoid. AI account security has quietly become just as important as protecting your email or banking login, because these chatbots now hold personal conversations, saved documents, and sensitive prompts that hackers can exploit if they slip through the cracks. TechCrunch has put together a detailed breakdown of how each major AI platform lets you check for suspicious logins and lock down your account if something looks off.
Key takeaways
- Hackers can target and break into accounts on AI platforms including ChatGPT, Claude, and Perplexity, just as they do on any other online service.
- Multi-factor authentication is available on ChatGPT and Perplexity, but Claude skips passwords entirely in favor of email login links.
- ChatGPT and Claude both let users view active sessions and log out of suspicious devices; Perplexity hides session details but allows signing out of everything at once.
- ChatGPT users can reset a password using a six-digit code sent by email, while Claude has no password to reset at all.
- Logging out of all devices is the fastest first step if you suspect your account has been compromised on any of these platforms.
AI Platform Accounts Are Targets for Hackers
AI chatbots are not immune to the same threats that target social media accounts, email inboxes, or messaging apps. Just like any other online service, hackers can target and break into accounts on popular AI platforms such as ChatGPT, Claude, and Perplexity, according to TechCrunch’s cybersecurity coverage. That matters more than it might seem at first glance, since these platforms often store long histories of personal or professional conversations, uploaded files, and account-linked payment information.
TechCrunch has created a comprehensive guide to help users protect themselves if they suspect someone has broken into an account on one of these platforms — building on similar security walkthroughs the outlet has published for other major internet services. The guide focuses on a practical question: how do you actually check, right now, whether your AI accounts are secure?
How to Verify and Manage Active Sessions on AI Platforms
Each of the three platforms offers a way to see or manage where your account is logged in, though the level of detail varies quite a bit from one service to another. Reviewing active sessions is the single most direct way to spot an unauthorized login before it turns into a bigger problem.
Checking and Logging Out of Sessions on ChatGPT
To find out if someone has broken into a ChatGPT account, open the platform in a browser, click on your username in the bottom-left corner, go to Settings, then Security and Login, and select Active Sessions. This shows every device currently logged into the account. If a device looks unfamiliar, users can log it out individually, or click Log out all to close every session at once.
Session Management on Claude
On Claude, the process is similar but lives in a different menu. Open Claude in a browser, click your username, go to Settings, then Account, where Active sessions appears. Hovering over an unrecognized session reveals three vertical dots with options to Log out or Terminate that specific session. Users can also select Log out of all devices to clear everything in one move.
Session Controls in Perplexity
Perplexity works differently. The AI-powered search engine does not show where you are logged in, so there’s no list of devices to inspect. Instead, anyone worried about unauthorized access can go to their username, open All settings, and click Sign out of all sessions, followed by Confirm. It’s a blunter tool than ChatGPT’s or Claude’s session lists, but it still achieves the same goal: cutting off anyone else who might be logged in.
Across all three services, logging out of every device is the recommended move the moment an account compromise is suspected, even before figuring out exactly how someone got in.
Authentication and Password Management Differences
The three platforms don’t handle logins the same way, and that difference shapes how each one should be secured. Multi-factor authentication is recommended and available on ChatGPT and Perplexity, adding a second verification step beyond a password, but Claude skips this entirely.
Multi-Factor Authentication and Passwordless Login
Claude doesn’t offer MFA because Anthropic’s chatbot doesn’t use passwords at all. Instead of a login screen asking for a password, Claude sends a login link straight to the account’s email address. That makes email account security effectively the front line of defense for Claude users — if someone controls the inbox, they control the Claude login too.
This is one of the more notable contrasts among the platforms: while ChatGPT and Perplexity users benefit from an added multi-factor authentication layer for AI platforms, Claude users depend entirely on the strength of their email provider’s own protections.
Password Reset Process on ChatGPT
For ChatGPT, changing a password first requires logging out of the account. From ChatGPT’s login page, users click Log in, enter their email address, then select Forgot password and Continue. ChatGPT then emails a six-digit code, which gets entered on the login page before setting a new password. The email also includes a direct “reset your password” link with official instructions, offering a second way to complete the same process.
Why a Dedicated Security Guide Matters
As AI chatbots become storage vaults for personal notes, work documents, and sensitive prompts, checking for a hacked ChatGPT account or an unfamiliar Claude login has become a genuinely practical skill rather than a niche cybersecurity concern. TechCrunch’s step-by-step breakdown for ChatGPT, Claude, and Perplexity gives users a concrete checklist rather than vague advice, walking through exactly which menus to open and which buttons to click on each platform.
Step-by-Step Protection Across Platforms
The guide’s core message is simple: check active sessions regularly, use unique passwords stored in a password manager where passwords still apply, and turn on multi-factor authentication wherever it’s offered. The article was written by Lorenzo Franceschi-Bicchierai, a Senior Writer at TechCrunch who covers hacking, cybersecurity, surveillance, and privacy — giving the guide added weight as a resource for everyday users navigating unfamiliar security settings on newer AI tools.
FAQ
How can I check if my ChatGPT account has been hacked?
Open ChatGPT in your browser, go to Settings, then Security and Login, and select Active Sessions to see which devices are logged in. From there, you can log out a suspicious device individually or log out of all sessions at once.
Does Claude use passwords for login?
No. Claude uses a passwordless login system that sends a login link directly to your email address instead of asking for a password.
Is multi-factor authentication available on all these AI platforms?
Multi-factor authentication is available on ChatGPT and Perplexity, but not on Claude, which relies on email-based login links instead.
What should I do if I suspect unauthorized access on Perplexity?
Sign out of all sessions through the settings menu, then log back in using your email address and the unique six-digit code sent to you.
