I'm working on an AngularJS and PhoneGap app, and I need a way to generate a unique identifier for each user of the app.
It seems like getting the phone number from the device is not possible, can anyone confirm this?
If retrieving the phone number is not an option, are there any other methods I can explore?
Is there a unique identifier stored in the browser or device that I can access using JavaScript/AngularJS?
To ensure each instance of your application is unique, you can utilize the device.uuid method. The value returned by this method varies depending on the device manufacturer:
// Android: Generates a random 64-bit integer as a string upon first boot
//
// BlackBerry: Provides the device's unique nine-digit PIN number as a string
//
// iPhone: Creates a unique string using multiple hardware identifiers,
// guaranteed to be distinct for each device and not linked to user accounts
//
// Windows Phone 7: Produces a hash based on device and current user information;
// generates a GUID if no user is defined, which persists until app uninstallation
//
// Tizen: Retrieves the device IMEI (International Mobile Equipment Identity),
// a GSM and UMTS mobile phone identifier that is inherently unique
This method should suffice for distinguishing between different instances of your application.
