Respond to the notification by opening the Salesforce Authenticator app on your mobile device.The app displays details of your account activity, including your username, the service you’re trying to access (such as Salesforce), and information about the device used for the activity. If location services are enabled and available, the app shows the user’s current location. Owing to the nature of geolocation technology, the accuracy of geolocation fields (for example, street address, country, city) can vary.
