Accounts on popular AI platforms can be accessed by unauthorized parties. Below are the platform-specific checks and actions to see whether an account has been compromised and how to end other sessions.
ChatGPT
On a browser, click the username in the bottom-left corner, open Settings → Security and Login → Active Sessions to view devices currently logged into the account. From that panel it is possible to log out a single device or click “Log out all.”
To change a password, sign out of the account, then select “Log in” at the bottom-left, enter the email address and choose “Forgot password.” ChatGPT will send a six-digit code by email to proceed with a password reset or use the “reset your password” link in the message for official instructions. The platform supports multi-factor authentication (MFA).
Claude
Open Claude in a browser, click the username in the bottom-left, go to Settings → Account and check Active sessions. Hovering over a session reveals three vertical dots on the right; use those to Log out or Terminate single sessions, or choose “Log out of all devices.”
Claude does not use passwords. Anthropic’s chatbot relies on email login links to authenticate, so there is no password to change when terminating sessions.
Perplexity
Perplexity does not list where an account is logged in. To remove possible unauthorized access, click the username in the bottom-left, select All settings, then choose “Sign out of all sessions” and confirm.
After signing out, log back in by entering the account email; Perplexity will send a unique six-digit code or a sign-in link by email. The platform also offers multi-factor authentication.
The reporter Lorenzo Franceschi-Bicchierai recommends using unique passwords stored in a password manager and enabling MFA where available. For concrete account recovery steps: ChatGPT provides a six-digit reset code and a reset link; Claude re-authenticates via email links and has no password to change; Perplexity uses a six-digit code or sign-in link to regain access.
