Your Daily Tour of Approov Product Features

Hi there

By default, if you run your app in the Android emulator or iOS simulator then you won’t receive valid Approov tokens, even if the app is registered. This is because these platforms might be used to attack your app. But for your own development purposes it is possible to make a particular emulator/simulator always pass to make development easy. This also means you won’t need to register the app each time you change it.

Best Regards,

Approov Mobile Security
