3D PassGo Lock Screen

PassGo is an open source project available at https://github.com/3d-passgo

Have you ever used a 3D password? Try “3D PassGo”, the first ever 3D password, which will provide you with the coolest 3D experience and the unprecedented security.

PassGo, derived from Go (an accent Chinese board game), is widely believed to be the prototype of the Google Pattern Lock and to become the next generation password. In PassGo, a user draws lines and dots on a grid by touching the intersections as a password. According to the result of the scientific computation, the password space of PassGo is 256 bits, which is astronomical and is far more than enough to protect any mission critical data.

“3D PassGo”, further extends PassGo from a 2D plane to a 3D space. 3D PassGo is encoded as a sequence of 3D coordinates, and hence the password space is further extended exponentially. In addition, the 3D grid can be dynamically rotated like the earth in space, and be zoomed in or out to optimize your comfort to enter a password.

“3D PassGo” is also a superset of “2D PassGo”: i.e., a 1x3x3 3D grid is basically a 2D 3x3 grid; a 1x1x3 grid is a line, and a 1x1x1 grid is simply a dot. Therefore, you can enjoy all the features of 2D PassGo in 3D PassGo.

In "3D PassGo Lock Screen", you can fine-tune the security of your lock screen by adjusting the grid size from thousands of choices, from 1x1x1 all the way to 19x19x19. The color/style/background of PassGo can be easily customized to your own preference in a way of "you see what you get".

“3D PassGo”, adopting cutting edge technologies of Virtual Reality, make it possible to draw strong passwords easily.

FAQ

=============

* Why should I disable System Lock?

Disabling System Lock will avoid double locking. This is optional though.

* Screen does not lock, what is wrong?

Usually this is due to the setting of Lock Screen Timeout or the Lock Screen Service is not running. Try to turn on the Lock Screen Service. If the problem still exists, feel free to send an email to our support team [email protected].

* What is the "Lock Screen Timeout"?

"Lock Screen Timeout" is the wait time between screen is off and screen is actually locked. For example, if "Immediately" is chosen, then the screen will be locked instantly after it is turned off (due to either display timeout or power key is pressed); if "Two Minutes" is chosen, then screen will be locked two minutes after screen is off.

* How to rotate the grid?

Touch the screen just around the grid or inside the grid without touching any intersections, and then keep moving on the screen.

* How to zoom in or out the grid?

Place two fingers on the grid and then adjust the distance between the two fingers.

* How to move the grid?

Touch the screen without touching any intersections, hold for one second, (there will be a vibration and the grid will become dashed) and then the grid will start to move with the finger; in addition when finish zooming, you can also hold one finger for one second after lifting the other finger, and the grid will also move along the finger. (Note, moving grid only works on grid size smaller than 9x9x9)

* How to draw a dot?

To draw a dot, touch an intersection on the grid and then lift your finger.

* How to draw a line?

To draw a line, touch multiple intersections continuously and then lift your finger.
