Will another slot be taken in my licese after reinstalling Raspbian OS or Puffin?

We recognize slots in your license by individual devices.

If you reinstall Raspbian OS, reinstall Puffin, or replace the SD card from the Raspberry Pi, you will need to re-activate Puffin.

As it is the same device, it will not take another slot in your license.

*Note: We strongly advise against changing the hardware serial-number or other related information. Once the information is altered, our license system may consider the hardware model a different device and count it against your license.
