What Does iOS 27 Impersonation Risk Detection Do?
Impersonation Risk Detection is designed to help protect against active social engineering scams. For example, a scammer might pretend to be a bank employee or government official and pressure you into transferring money or changing your account information.
When a compatible app requests an assessment during a potentially risky action, the iPhone analyzes relevant signals related to device activity and the user's Apple Account. The app receives a risk level rather than the underlying information used to generate the assessment.
There are two important limitations to understand:
-
It doesn't automatically block every scam. The app decides how to respond to the assessment, such as displaying a warning, requesting additional verification, or delaying an action.
-
It doesn't work in every app. Only third-party apps that support Impersonation Risk Detection can request assessments. Enabling the setting does not activate scam detection across all apps.
Apple also states that the feature does not analyze the contents of your Photos, Messages, or Mail to generate its risk assessment.
Why Can't I Find iOS 27 Scam Prevention?
If you cannot find Impersonation Risk Detection in Settings, check the following:
-
Check your iOS version: Make sure your iPhone is running iOS 27 or later. The setting is not available on earlier versions.
-
Look in the correct menu: Go to Settings > Privacy & Securityand scroll down to findImpersonation Risk Detection.
-
Check your Apple Account: If prompted, sign in to the App Store with your Apple Account, then return to the setting.
-
Allow time for changes to take effect: After enabling or disabling the feature, wait up to 24 hours before checking the result.
-
Check app compatibility: The setting can be enabled even if none of your installed apps currently support the feature. This does not necessarily indicate a problem with your iPhone.
If the option is still missing, consult Apple's official iPhone user guide for the latest availability information.
FAQs About iOS 27 Scam Prevention
Is iOS 27 scam prevention turned on by default?
No. Impersonation Risk Detection is an opt-in feature. You need to enableShare with App Developersin Settings before compatible apps can request risk assessments.
Does iOS 27 scam prevention work in every app?
No. Only third-party apps that support Impersonation Risk Detection can use it. Turning on the setting alone does not activate scam detection in every app.
Can I turn off scam prevention for just one app?
Yes. OpenSettings > Privacy & Security > Impersonation Risk Detection, select the relevant app if it appears in the list, and turn off its individual access toggle if available. This lets you manage app access without necessarily disabling the feature for every compatible app.

Bottom Line
Enabling Impersonation Risk Detection adds another layer of protection for iPhone users running iOS 27. Turn it on under Privacy & Security if you want compatible apps to request risk assessments, or turn it off if you no longer want to share those assessments with apps. Either way, remember that the feature depends on app support and does not replace careful judgment when handling unexpected payment or account requests.
