To log in to Plesk, open your web browser and open the following address:
https://<host-name-or-IP>:8443
The Plesk login page will open.
Select the desired interface language and type in your username and password to log in to Plesk. By default, your username is admin and your password is setup, but these may have been changed if Plesk was pre-installed by a third party. Alternatively, you can log in to Plesk using the root username (on Linux), or the administrator username (on Windows), and the corresponding password.
Note: You can disable logging in to Plesk with the root or administrator credentials. To do so, edit the /usr/local/psa/admin/conf/panel.ini file (on Linux) or the C:\Program Files (x86)\Parallels\Plesk\admin\conf\panel.ini file (on Windows) and add the systemAdmin = false line to the file.
