I am very nuanced, you just don’t get it. I don’t use that tool, so I ask questions to understand what’s going on.
If fingerprints are always an additional part, that’s kinda okayish. It is not even a real second factor, because it is too easy to steal and you cannot change it (similar to the DNA test on the other thread). But at least okayish. I still would not recommend it on any situation.
The thing is, as more we’re using biometrics as security token, as more it becomes a value to get abused. And this becomes also a danger for people who’re not using fingerprints for such things. Let’s say everyone uses it, how easy it would be for a restaurant to catch your fingerprints and match them with your name they get by paying with any bank card? People buy a lot of money for such information (data bases with many datas) on internet. How easy is it to get it from phone itself? One time uploaded, compromised for the whole life. Even for people who don’t use it right now, once their fingerprints are uploaded, it cannot be used any time longer in future such things. In fact it is as secure as super easy passwords, just that passwords can be changed at any time.
And again, I made a question. I do not know what features are opt-in of software I do not use or if opt-in means it’s the only thing you have and just wanted to know this, because that was very much what I was reading out of your text without additional context. So maybe you should be more nuanced when speaking about people you don’t know/understand.
