Factory reset of nitrokey 3a

Hello!
can anybody tell me the functionality of both these.

  1. nitropy nk3 factory reset
  2. gpg card factory reset.
    i mean if i perfrom first one, is this also remove keys from gpg card or i need to do a factory reset of gpg card along with device factory reset(nitropy nk3 factory reset)?
    Does both are required for complete reset of device or just one functionality can perform whole reset?

you can choose

U didnot understand my question. My point of asking this question was, when i do a factory reset of device using nitropy, still do i need to factory reset of gpg card or not?

You can choose what you reset. A full reset of all applications include opcardrs and thus wipes your OpenPGP credentials.

factory reset using gpg --card edit commands erase data from open pgpg card only? or does it removes fido keys and other data from nitrokey?

Only the data of the opcard-rs app. Other secrets are separate.
