That's sound advice but I'd like to point out that this Open PGP card appears to only support 2048bit keys while some (but not all!) yubikeys and nitrokeys support 4096bit.

I suppose nowadays 2048bit is more than enough but I like the extra safety and "future-proofness" of a 4096bit key.

I'm definitely with you, and don't advocate for 2048 bit keys anymore. That being said...

The older versions of the card only supported 2048bit keys. The 2.0 version and above support 4096 :)

I personally generated my RSA4096bit key on the card!
