I bought a Nitrokey Pro 2 and my plan is to use it to store three OpenPGP subkeys (authentication, encryption, signing).
My master key is elsewhere.
The problem I encountered is that while the three subkeys are on the Nitrokey, the passphrase is not asked when I try to decrypt a file or sign a mail, for example. Only the user PIN is asked.
I do not fully understand the mechanism going on. When the subkeys were on my computer, the passphrase was asked each time I tried to sign or encrypt a message.
Can you help ?
Thanks in advance.
