- LeifCarrotson 9y agoSure, but you can't do that if you're a web page. This is about a malicious app or website listening to the accelerometer and gyro to determine what the user is typing on the keyboard into a separate app.
- collyw 9y agoI noticed this when holding my phone at an angle so the light made the smudges completely obvious.
- fao_ 9y agoThis is why I chose one that doubles back on itself in a non-obvious way. I've tested it by trying to teach people the password, it usually takes them quite a while to learn it, even when I do it really, really slowly and give them lots of tries
- ballenf 9y agoLast time I used this on Android, there were 9 points but I couldn't use any one more than once. You can double back in a very limited way, but the more complex patterns I wanted to use were impossible. I'm sure there's more written on this, but most patterns I've seen are just way too short. And hug the outer edge, are in-order, etc.
