As I need an Ed25519-SK SSH key generated with a hardware token, I tried to use my Nitrokey for that, but: no.

Years ago, had experimentally been added to the firmware (not released) but later stated that customers should've donated on top of the selling price to get firmware updates & advised to buy the new product instead.

The latter would be OK if the old key wasn't sold anymore, but it is still sold & the firmware was last updated in 2021.

Besides the FIDO2, I also already have a Nitrokey U2F & a Solo Somu from , so I wasn't too keen on paying 50€ + shipping for a new Nitrokey 3A Mini – a product I wouldn't need if my old key's firmware had been updated.

Instead, I bought a 🇨🇭 Token2 PIN+ Dual R3 whose hardware and firmware is also open-source and which costs only 25€ + shipping: token2.eu/shop/product/pin-dua

The only downside is that manufacture their products outside Europe (Nitrokeys are made in 🇩🇪).

I didn't buy that Token2 model because of its NFC capability and USB-C connector, but because it's the cheapest token supporting Ed25519-SK. I did try out using it with my 3 running /e/OS with , and it worked fine.

The silicon case I ordered along with the key is unfortunately a bit too thick and thereby prevents the key's USB-C connector from being inserted properly into the FP3 if it's wearing its rubber case as well, which makes NFC a bit tricky too.

The packaging of the Token2 PIN+ Dual R3 is red and decorated with a couple security icons as illustrations in the background. Under see-through plastic resides the security key with a USB-C connector on the left and a USB-A connector on the right. The key itself is black and decorated with the same illustrations of keys, locks and password stars. The serial number written in text form and as a QR code is blacked out for secrecy. The actual name of the key is a bit ambiguous, because the main label in the middle reads just “PIN+ R3”, while the label in the top left reads “T2F2-NFC-Dual” and then “PIN+ R3” after a line-break. As their motto, Token2 have apparently chosen “Security is easy” (which is true for their product! 😉). The description text reads: “The PIN+ security key series enforces strong PIN complexity rules at the firmware level to ensure maximum security.” Besides the FIDO logo, there are notes indicating that the product was designed in Switzerland and that only keyrings at most 2 mm thick should be used.
The Token2 key wearing a white silicon case with caps that protect the USB-A and USB-C connectors and that are attached to the rest of the case with a silicon hinge. The case itself has a metal keyring.
