- scarface74 10y agoYour fingerprint is never sent to the app. The first time you use an app you have to enter your user name and password and that is stored in the secure enclave that not even the operating system had access to. When the banking app request validation, you use your fingerprint to authenticate and the secure enclave sends the username and password to the app. The fingerprint scanner is connected directly to the secure enclave. When you sell your phone, you go through the process of erasing your phone, the encryption key is destroyed and your fingerprint is no longer valid.
