You can do it with a lifted print, if you get a good one. But as you say, fingerprints are basically usernames with the advantage that not everyone can enter them. And I'm the only one who has my fingerprints on my fingers, it's a pretty basic proof of ownership right there.
We're back at the secure versus ease of use with temptation removal discussion now, I reckon I've touched on it before.
The only way to secure your house is to weld steel plate over the entire thing. Same with the phone.
But that's kind of ridiculous, because you want to text someone or lie down in bed sooner or later, so we compromise security for minimal personal impact while retaining ease of use.
So we use locks with keys, or cards, or rings. I love the Ring entry because set up right I can just straight-arm the door and walk in without stopping.
It doesn't mean the house is either more or less secure than before, but it's certainly [b:1k7d292k]easier for me to get into and just as difficult for someone unauthorised to get into[/b:1k7d292k].
They can still break a window, pick a lock, smash a door or climb through the roof. Or use a copy of your fingerprint if it's applicable.
But not everyone is going to go to that kind of [b:1k7d292k]effort[/b:1k7d292k] to get at your gear, and if they are willing to go that far then odds are that they would have just used a cutting torch on the original ultra-secure steel box around the house.
It's not a huge deal. Shrug your shoulders and move on, doing the best you can without wildly inconveniencing yourself and knowing that if someone really wants in then you can't stop them anyway.
[b:1k7d292k]Just enough to deter the average idiot[/b:1k7d292k] is the best balance in my opinion.
Still, back on topic - integrating the fingerprint reader on the samsung into the unlock app would be cool.
