Off the grid
Free AppAbout Off the grid
Off the Grid is effectively a password manager that will help you create different passwords for different websites. Passwords are generated by simply typing in text - the program will use a Latin square (of Sudoku fame) to scan for the password using a specific pattern. The generated Latin square (grid) can be printed out and kept safe so that passwords can be retrieved without a device.
This application is a tribute to GRC's work on password generation using Latin squares: https://www.grc.com/OffTheGrid.htm
OTG (Off the Grid) is particularly useful for sharing passwords. You can simply generate a grid and then scan in the QR code on each persons device; they will then all be able to retrieve the password for "example" by simply typing in "example".
This password sharing could be useful for couples/colleagues with various shared accounts or
IT departments that need to access the same servers with the same password.
The following permissions are used:
android.permission.CAMERA - this is to capture the QR codes for previous grids.
android.permission.INTERNET - this is used to collecting analytics on usage of the application. android.permission.WRITE_EXTERNAL_STORAGE - this is used to temporarily write an encrypted zip file to so it can be emailed.
android.permission.WAKE_LOCK - this is used to keep the screen on while the password is displayed.
There is no master password, so it is advised that you also have a remote wipe tool and lock code for your device.
Warning: this app should NOT be used if your device has been rooted. Why? - Off the Grid relies on being sandboxed by Android; when you root your device other applications may be able to read inside the sandbox created for it.

Works very well. I used to only have to remember one password to open my password storage. Thanks to this app, it's now zero. Please release a pc version as well.

Nice implementation. Can I ask that you include a demonstration (similar to how Steve presents it) on your particular implementation? I notice that you seem to always go right and down on the grid when finding a starting point, then left and up when encyphering the key. This is slightly different to Steve's method and may confuse some people who wish to use both your app and an offline copy. Otherwise, I really like it and I think I'll use it. Especially after the recent security now episode on passwords.

I used the same passwords for different sites before using this. I have been told it's more secure this way. Nice and easy to use!

This is a fantastic app with the exact options I wanted. Thank you so much for the work!! I am a huge fan of grc and this app works great with Latin squares! I have a firewall on my HTC(non root) and I have only seen one outbound packet to a web address in Sunnyvale California going to a Yahoo hosted site. This seems to match what the dev said about analytics for app usage. No ads and perfect running makes this a must!
