[Q] How to transfer an app from one android phone to another? (special case)

Here is the problem;
I have a mobile banking app on my phone. The app is in the store and can be downloaded, but it has to be activated in order to be able to use it. So every time time I change the phone (and I do that once or twice a year), I have to go to the bank to get the code. I understand that this is a security measure. However, I'm so sick of this, that I'd like to try solving it.

Now, I'd like to be able to transfer that app to another phone without going to the bank/getting the new code. Is there a way to do this?
