FreeOTP+ on android does have "android hello" integration. In other words, I can hook it up to my fingerprint, same like my bank apps. Always remember: security is like onion skin and works best in layers. The more layers we have - the better. That's because not everyone's use case is the same and not all hacking attempts are the same. Here's a simple example: if I'm using a portable browser that already has all of my passwords saved, and I'm using your app in portable mode, then, a hacker can have all of my keys just by getting my files, even from a backup. So, as always, striking a balance between convenience and security is a delicate matter, and every little bit of that onion skin matters. Thanks.
