It is difficult to say this, but there is no way to make your Ionic app really uncrackable. Once you have completed your app and pass it on to the public, if a hacker, would like to know how your app works, he/she, given time, would be able to crack open your code someway or another. This, perhaps, is the weakness of not only hybrid mobile apps, but any mobile apps in general.
It is akin to passing a tinkerer a cuckoo clock that you have just built. If the tinkerer is competent, he/she would, in due time, find out, what makes your clock ticks.
However, there are ways to make it a little bit difficult for the “tinkerer” to see what is going on behind your app. Here are 5 ways to make your Ionic App more secure.
1. HTTPS versus HTTP
This is already a standard on the latest Android and iOS updates. Unless you are debugging, it is a requirement that any connection to a server to be done via HTTPS. (Note the S at the end, which, obviously stands for secure)
HTTP (without S) connection is vulnerable to exploits and connecting to via HTTP is not recommended.
2. SSL Pinning
Another way to make your app secured, if you need to connect your app to a remote server, is to do an SSL pinning connection.
