You use the Plesk administrator username and password to log in to Plesk. By default, the Plesk administrator username is admin.

However, admin is a predictable username, which can be easily guessed and used in brute-force attacks. Along with a strong password, you can set a custom username as an additional layer of protection against brute-force attacks.

To change the Plesk administrator username:

  1. panel.ini ファイルを編集用に開きます。ファイルは以下の場所にあります。

    • (Plesk for Linux) /usr/local/psa/admin/conf/panel.ini
    • (Plesk for Windows) %plesk_dir%admin\conf\panel.ini

    Panel.ini Editor 拡張を使用すると、Plesk インターフェースでもファイルを編集できます。

  2. panel.ini ファイルに以下の行を追加して保存します。


    You can now change the Plesk administrator username in the Plesk interface or via the CLI.

  3. [マイ・プロファイル]を開きます。

    image admin username

  4. The "Plesk Preferences" section now contains the "Username" text field. Change the default admin username to a custom one, and then click OK.

    注釈: To change the Plesk username via the CLI, run the plesk bin admin --set-login <custom_username> command.

You now need to use the custom username to log in to Plesk.
