picture login and lock screen

[fbd-ss]

I use picture login and lock screen on windows and love it.
It is an option available to replace using a password or pin to login.

In the above picture to login you select 3 points on the picture and if correct it logs you in.

Out of all windows 10 features this one was and still is my favorite, hard to brute force, easy to rember, and basicly impossible to blindly guess.

Even a 1080x720 image has 777,600 pixels, even if you set a 100 pixel allowence, that would require a human to guess 2,592 times with perfect mouse movments, and now images with 1680x2060 resulutions, which would be many times better.

If the image was read only, and the gui options allowed the user to set the sensitivity, with the option to fallback to a standard password after 3 failed attempts, It would be a very welcome feature by me.

The chance, guesses and screen reslution choice may include some missunderstandings over how to properly calculate them so take them with a grain of salt.

The tricky part would handling different screen resultutions, sizes, and ratios without requring the user to recalibrate the picture lock.

Forgot to add: being able to chose how many spots you need to click to touch, with a range from 1-10 would be a great bonus.
