Lock Pattern Generator

Program Help

Lock Pattern Generator is a program for creating random patterns to lock your Android device with.

Why can't Lock Pattern Generator set the pattern for me?

If programs like Lock Pattern Generator were able to set your lock pattern, it would be possible to write a program that set an extremely hard pattern without your knowledge to deny you access to your own device. This wouldn't be hard to get around; Android allows you to sign in with your Google ID if you fail the pattern too many times, but it would still be a large security hole in Android. If you want Lock Pattern Generator to be able to set your pattern for you, file a bug report with Google.
Also, if you didn't have to enter the pattern yourself to set it, you'd be more likely to forget your new pattern!
To make the process of setting your pattern a little less tedious, there is now a button under the generate button that will take you straight to the Android security settings so you can set your shiny new pattern there. Try it!

Basic use

Lock Pattern Generator is ready to use right out-of-the-box. Simply click 'Generate' and a reasonable pattern will be generated for you. If you want to use it, simply memorize it (which is rather necessary anyway), and click the 'Android Security Settings' button. This will take you to the security section of Android's settings program. From there you can set your new pattern, at which point it will be active. If you already had a pattern or other lock set, you'll need to enter it before Android will allow you to set the new one.
If you're having trouble identifying where the patterns start, try checking 'Highlight First Node' on the settings page.

Practice mode

If you want to practice your pattern a few times before setting it, simply click the practice toggle next to the 'Android Security Settings' button. While practice mode is active, you cannot generate new patterns, but you may draw patterns on the grid. If the pattern you draw matches the last pattern generated, the nodes will glow blue. If your pattern does not match, the nodes will glow red.

Custom generation parameters

The default settings are intended to work well for the vast majority of people. The patterns are a minimum length of 4, which is the minimum Android will allow, and a maximum length of 6, which is still in the realm of easily-remembered patterns.
If you don't like those bounds, you can easily set both the minimum and maximum lengths on the settings page.
