summary: By default, the Plesk administrator username used to to log in to Plesk is admin. However, it is a predictable username, one which can easily be guessed and used in brute-force attacks.

To make your Plesk server more secure, besides setting a strong administrator password, you can set a custom administrator username as an additional layer of protection against brute-force attacks.

In this topic, you will learn how to change the default Plesk administrator username.

To change the Plesk administrator username:

  1. Log in to Plesk.

  2. Go to My Profile.

    image admin username

  3. Under “Plesk Preferences”, change the default admin username to a custom one, and then click OK.

    Note: 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.
