ChatGPT Unusual Activity Detected From Your Device

Workaround available Web, Windows, macOS, iOS, Android Updated October 21, 2026

Quick answer

'Unusual activity has been detected from your device' appears when your traffic looks automated, most often because you share a VPN or proxy IP with many users. Turn off the VPN, use a private window, and secure your account.

Most likely fix: Turn off VPN, proxy and security extensions.
