@sosthene-nitrokey just want to make sure we are at the same page:

<nk3

HOTP code verification application, version 1.7
Connected device status:
Card serial: 0x7BE66C6C
         Firmware Nitrokey 2: v1.7.1
OpenPGP smartcard PIN counters : Admin: 3, User: 3
Operation success

nk3:

         Firmware Nitrokey 3: v1.7.1

This is not the same command. This is pin-info, see #39 which is distinct from #38.

I still see 2 pins instead of one secret app PIN?

[nestire]

works with nk pro, nk stroage, nk3 mini, nk3.

Since this should only be used for parsing within heads to output it like that is actually better since it we don't need then different parsing for nk3

I see two pins when there is only one still...

You proposed :

See also issue #36
Change this:

HOTP code verification application, version 1.6
Connected device status:
	Card serial: 0x7BE66C6C
	Firmware: v4.13
	Card counters: Admin 6, User 6
Operation success

To

HOTP code verification application, version 1.6
Connected device status:
	Card serial: 0x7BE66C6C
        Firmware Nitrokey 3: v1.7.1
	Firmware Secrets app: v4.13
	Secret app pin counters : Admin 6, User 6
Operation success

I proposed and restated:

Even more sensical: no secret app even named anywhere because there is none on non nk3(regression), so no version of non existing secret app, no secret app pin, just real information :

HOTP code verification application, version 1.7
Connected device status:
Card serial: 0x7BE66C6C
         Firmware Nitrokey 2: v1.7.1
OpenPGP smartcard PIN counters : Admin: 3, User: 3
Operation success

For nk3:

HOTP code verification application, version 1.7
Connected device status:
Card serial: 0x7BE66C6C
         Firmware Nitrokey 3: v1.7.1
         Firmware Secrets app: v4.13
Secret app PIN counter : 6
OpenPGP smartcard PIN counters : Admin: 3, User: 3
Operation success
