With dynamic provisioning, you can use Blynk.App to configure connection credentials for each device. You can use the same firmware binary for all of the devices of the same type.

Production Line provisioning support
This allows you to configure device credentials and other device-specific parameters on the device production line. You can use the same firmware binary for all of the devices of the same type.
The feature is currently under development, and available upon request.
Static provisioning support
With static provisioning, authentication tokens are incorporated into the firmware binary. This method is supported by the vast majority of hardware platforms.
This is the easiest way to migrate legacy Blynk projects. Just add BLYNK_TEMPLATE_ID and BLYNK_DEVICE_NAME on top of your existing firmware (before any Blynk includes), set new Auth Token and that's it. Read more about project migration.
