Question

So, what is the best way to store secret?

Answer 1

There is a Web API which could be used for secure storing application data - tizen.keymanager.saveData . You can use it for storing some string data and protect this with password - it seems to fit your needs.

Additional feature is that you can share access to this value between several applications, by setting permission.
