I repeat

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
