ユーザーパスワードを要求せずに、pemキーを介してSSHを介してリモートサーバーにアクセスします。

sshリモートサーバーはパスワードで保護されたキーのみを使用してpemアクセスしたいが、ユーザーアカウントのパスワードも提供する必要があります。

次のコマンドを使用して、ホストからログインするときに使用するアカウントを作成しました。

sudo useradd -d /home/admin -m -G sudo admin

私のpemキーはパスワードで保護されているので、2番目のパスワード（キーパスワードとユーザーパスワード）を設定せずにキーファイルのパスワードのみを求めるメッセージを表示したいと思います。どちらも尋ねるメッセージではありません。

どうすればいいですか？

EDIT1：pemPuttyGenを使用して鍵を生成し、公開鍵と秘密鍵を保存してから、pemOpenSSHキー（）にエクスポートしました。その後、公開鍵を~/.ssh/authorized_keysファイルに追加しました。

EDIT2：リモートサーバーにアクセスできますが、2つのパスワード（キーとユーザー）を入力する必要があります。パスワードを入力したいです。なるべくpemキーのパスワードを入力したいです。

$ ssh -i admin.pem [email protected]

Enter passphrase for key 'admin.pem':
[email protected]'s password:

編集3：これは結果ですssh -vvv -i admin.pem [email protected]
