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. 打開位於此處的用於編輯的 panel.ini文件：

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

    您還可以使用`Panel.ini Editor <https://www.plesk.com/extensions/panel-ini-editor/>`__ 擴展在Plesk介面中編輯該檔。

  2. 添加以下各行到 panel.ini 檔並將其保存：

    [login]
allowChangeAdminLogin=true

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

  3. 轉入 我的個人資料 。

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

    備註: 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.
