LAContext change UIAlertController button title

I've incorporated TouchID into my app with LAContext, like so:

enter image description here

However, I'm wanting to change the name of the button title from "Enter Password" to enter "Enter Security Code" (or something like that), like this:

enter image description here

How would I go about changing that button title?

Here's the LAContext documentation and here's my code:

var touchIDContext = LAContext()

if touchIDContext.canEvaluatePolicy(LAPolicy.DeviceOwnerAuthenticationWithBiometrics, error: &msgError) {
   touchIDContext.evaluatePolicy(.DeviceOwnerAuthenticationWithBiometrics, localizedReason: touchIDMessage) {
        (success: Bool, error: NSError!) -> Void in

        if success {
            println("Success")
        } else {
            println("Error: \(error)")
        }
    }
}

From Apple Documentation, localizedCancelTitle is available for iOS 10

// Fallback button title.
// @discussion Allows fallback button title customization. A default title "Enter Password" is used when
//             this property is left nil. If set to empty string, the button will be hidden.
@property (nonatomic, nullable, copy) NSString *localizedFallbackTitle;

// Cancel button title.
// @discussion Allows cancel button title customization. A default title "Cancel" is used when
//             this property is left nil or is set to empty string.
@property (nonatomic, nullable, copy) NSString *localizedCancelTitle NS_AVAILABLE(10_12, 10_0);

Set the localizedFallbackTitle property:

Objective-C:

LAContext *context = [[LAContext alloc] init];
context.localizedFallbackTitle = @"YOUR TEXT HERE";

Swift:

var touchIDContext = LAContext()
context.localizedFallbackTitle = "YOUR TEXT HERE"
