Hi, Thanks for answering. What you comment makes a lot of logic. One of the things I try is to ensure that there are no security leaks. A user could pass the cell phone to another person and register their fingerprint (up to 4 are allowed) and use the app without problem. That's why it seems important to me that the footprint can be created and managed from the app.
