GridUnlock is a handy security tool. It supports websites and other applications that use grid authentication (see: http://gridunlock.tumblr.com/whatisit). The beauty of this app is it eliminates the need to carry around your unique grid in physical form, such as a card. All you need is your phone. Once you have entered the grid coordinates into GridUnlock, this app will provide you the values required to log you on.
If you would like to support the development of GridUnlock, please purchase the pro license. The pro license unlock additional features.
Import grids in CSV format
Import grids from Lastpass to provide two factor authentication (grid authentication)
Ability to store multiple grids
Grids are encrypted while stored on the phone with AES encryption
Application Backup and Restore to sdcard (Pro only)
GridUnlock should be compatible with any bank, website or application that uses grid authentication. The following list is not exhaustive but does show some of the websites that GridUnlock should work with. If you are using GridUnlock with another website or application then let us know so we can add it to this list.
Lastpass (Two Factor Authentication also known as Grid Multifactor Authentication)
Also compatible with Credit Cards with grid values printed on the back. These cards often only have one row which does not have a row label. Simply enter A as A1, B as B1, C as C1 and so on.
If you find GridUnlock it not compatible with a website that uses grid authentication please contact us and we’ll do our best to rectify the issue.
Photos / Media / Files permission is required to backup the application configuration.
We'd love to hear your feedback so we can improve GridUnlock.
