How is this secure? There are only 15 choose 3 different possible logins for each screenful of pictures. That's 455. So you have a 1/455 chance of just guess

How is this secure? There are only 15 choose 3 different possible logins for each screenful of pictures. That's 455. So you have a 1/455 chance of just guessing the right one? Or does order matter? Maybe that's what's happening. 15 permute 3 is 479,001,600.
- almost 19y agoEven then, how is would that be more secure than a password?
- seren6ipity 19y agoNo, the order does not matter. You can enter code from the three slides in any order. I've checked at their website.
- nickb 19y agoHad you actually read through or watched the video, you'd notice that you can't just take someone's username and start guessing. They have a second layer that requires "out of band" authentication. http://www.vidoop.com/vidoop_how.php http://www.vidoop.com/vidoop_how.php Also, it's more like 12 choose 2 but you cannot enter those two easily since: they change all the time and they're embeded in pictures.
- herdrick 19y agoI misread 12 as 15. But the blog post says you pick three images. So 12 choose 3, or 220. OK, if you were willing to sit through their video, why don't you tell us about this second layer?
