By default, EditionGuard's download links are limited to one device only, ensuring the security of your eBooks. However, to allow your readers to access your eBooks on multiple devices, uncheck the "restrict to single device" option in your account dashboard. It will let your readers download your eBook on six different PCs and six devices like phones and tablets. While there is no option to limit the number of devices to a number in between, allowing up to 6 devices provides flexibility while maintaining control over your eBooks' distribution. Additionally, if you allow more than one device, all subsequent activations will require the same Adobe ID for added security.
