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。

    [login]
allowChangeAdminLogin=true

    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.
