This add-on module helps safeguard Microsoft Access Applications from software piracy. It also enables developers to generate secure trial/shareware versions of Access databases and to enforce monthly, quarterly, semi-annual, or yearly software license renewals.

By using KeyedAccess, you can ensure that only the key you provide unlocks the full functionality of your application. Any attempt to overwrite, modify or copy your application by software pirates is prevented. The software is protected from actions such as reinstalling, restoring the registry and backdating.
With KeyedAccess, end-users must enter a key that is validated to unlock the full features of your application. This allows you to create trial/shareware versions which restrict certain functionality until registration and validation keys are received by the end-user.
KeyedAccess also offers an "Installation Serial Number and Unlock Code" mode, which restricts the use of unlock codes on other computers. This makes it impossible for users to install your application on different computers without seeking permission from you.
In addition, a 16-digit Reg ID/Product Key mode is available where registered users can unlock the application, but it can be used on any computer. KeyedAccess provides an easy-to-use Wizard that guides users through the setup process.
Users can configure KeyedAccess to require a key for the application’s opening, or they can allow a trial period where full functionality is allowed for a specific number of days, sessions or table record insertions. Additionally, users can offer a monthly, 3-month, 6-month, or yearly license renewal requirement to ensure continued functionality of the application.
Overall, KeyedAccess is an excellent add-on module to ensure the security and validation of your Microsoft Access application. It is compatible with versions 97, 2000, 2002, 2003, and 2007.
