To call this "security" is funny in my opinion, can't any application also fetch the serial number? And also do they not get saved in logs like dmesg?

- vivid242 7mo agoIf you can restrict the software, this would be a good way for controlling physical user ‚presence‘ - like in the supermarket, when a supervisor needs to scan their card for a cash register to take out a wrongly scanned item. I like it!

Was recently watching a video on the RFID tags that Bambu Labs use on their spools and not only is the tag data encrypted, it's signed so even if you bypass the encryption, you still don't have a way to spoof the signature.
- vel0city 7mo agoIf they're just files on a flash drive, what stops someone from just copying the files to another drive? Its just moving the same issue up a level in the stack, and in many ways making it easier to clone it. One of the whole points of authenticator devices is that the actual key material isn't directly readable. You shouldn't be able to trivially reproduce the device.
