If you believe someone has used your Netflix account without your permission, you can check your recent viewing activity to see which titles were viewed. You can also check your Recent device streaming activity page, which will display the date and time of access, the country, state, and IP address the content was streamed from, and the device type used to stream. Please note that location information is approximate and determined by where the detected IP address is registered.
If you're seeing unexpected streaming activity on your Netflix account and none of your devices have been stolen, we recommend you change your Netflix password to make sure no one else can access your account without your permission. You can also sign out of all devices connected to your account to disconnect any unauthorized devices. This method of deactivation will disconnect all devices currently connected to your Netflix account, but may take up to 8 hours to take effect. This method will also clear the location data associated with your devices, so do not deactivate your devices this way if you believe your device has been stolen.
