Question Is the bluetooth keyboard encrypted without pass code?

[ohm-ish]

Hi
I just got a NuPhy Air96 V2 keyboard that has both 2.4ghz and bluetooth.
I asked them if it's encrypted, they said "yes the bluetooth connection uses encryption"

But when I paired it with my Windows 11 computer, it didn't ask for a pass code..
So this would mean that it's NOT encrypted.. right?
Or could it use some kind of automatic encryption that doesn't require user to enter a pass code?
This would be new to me

if it has encryption it`s automatic, you dont need to do anything.

Ok so the "enter pin/passcode to pair" is an old outdated thing?
I would like to confirm that it's encrypted, somehow

Enter pin to pair is not encryption. That's just to ensure you have access to both devices at time of initial pairing.

Each time they pair is when the encryption is established between the 2 devices. Do a quick search for "Bluetooth encryption" and you get plenty of hits as to how it works.

You are confused.
1. ANY Bluetooth device must use a code to pair with a Bluetooth host. Virtually all come with some default code installed, and allow you to change that if you wish. MANY systems require that you enter that code when you first pair it, but some systems may simply try out a couple of VERY common default codes like "0000" or "1234" and, if that works, you will not even be asked. It appears that is what your system did. I suspect this is the "code" you were asking the seller about.

2. "Encrypted" normally means that AFTER the device is paired and IS communicating with the host, all of the digital data being exchanged will first be encoded with some proprietary algorithm and code key that BOTH the host and the device must use. The sending unit codes the data, and the receiving unit decodes. In your case the keyboard is the device, and the software driver for that (which receives the encoded data via the Bluetooth communication system) decodes because it was supplied by the keyboard maker and HAS the required coding key and algorithm. THIS is what the seller THOUGHT you were talking about when you used the word "encrypted".
