How to Detect Hacked Accounts on ChatGPT, Claude, and Perplexity

TechCrunch has published a guide on how to check if your accounts on AI platforms like ChatGPT, Claude, and Perplexity have been hacked. The guide emphasizes using unique passwords stored in a password manager and enabling multi-factor authentication (MFA) for added security. ChatGPT and Perplexity offer MFA, while Claude does not, instead relying on email login links. To check for suspicious activity on ChatGPT, users can navigate to Settings > Security and Login > Active Sessions, where they can log out unrecognized devices or all sessions. For Claude, users can go to Settings > Account > Active sessions to manage devices. Perplexity does not display active sessions, so users are advised to sign out of all sessions and log back in with a six-digit code sent via email. The guide provides step-by-step instructions for each platform, including how to reset passwords for ChatGPT and how to re-authenticate for Claude and Perplexity.
