ファクトリーリセット¶

The multiple identities feature allows to use 3 virtual smart cards in place of one, giving bigger flexibility in the every day use, as well as separation between user identities (business, personal etc.) or even allowing usage of it for more than one user (PINs are separate).

All of the smart cards have separate data objects, meaning they all could have different keys, certificates stored, and PINs set. Identities do not interact between each other.

This means each identity needs to be reset on its own.

ファームウェアの古いバージョン（1.2.5以下）では、特別な処置が必要な場合があります（下記参照）。使用方法 -----

IDを変更するには、カスタムCCIDコマンドを送信すれば十分です。これは``pynitrokey``ツールで実現できます。

Install pynitrokey.

Nitrokey Startを接続し、認識されたことを確認してください。

$ nitropy start list
   *** Nitrokey tool for Nitrokey FIDO2 & Nitrokey Start
   :: 'Nitrokey Start' keys:
   FSIJ-1.2.15-87042524: Nitrokey Nitrokey Start (RTM.10)

<ID>``を``0``に置き換えて、アイデンティティを変更します。``1、または``2``となります。

$ nitropy start set-identity <ID>
   *** Nitrokey tool for Nitrokey FIDO2 & Nitrokey Start
   Trying to set identity to <ID>4
   device has reset, and should now have the new identity

リセット ¶

$ gpg --card-edit

メニューで`admin`と入力し、次に`factory-reset`と入力する。

This will reset the current identity. To reset all identities the following needs to be done:

$ nitropy start set-identity 2`
$ gpg --card-edit` -> admin -> factory-reset
$ nitropy start set-identity 1`
$ gpg --card-edit` -> admin -> factory-reset
$ nitropy start set-identity 0`
$ gpg --card-edit` -> admin -> factory-reset
