Hi,
These command will help you to manage your Plesk password from the backend.
--------------------------------------------------------------------------------
1) To obtain the current 'admin' password, execute this command in command prompt:
"%plesk_bin%\plesksrvclient" -get
2) To retrieve the password in command line you can also use the -nogui option [in case you are in CLI mode]:
"%plesk_bin%\plesksrvclient" -get -nogui > c:\plesk_passwd.txt
After that you can view the retrieved Plesk password in c:\plesk_passwd.txt file.
3) To set a new admin password execute the following command in command prompt:
"%plesk_bin%\plesksrvclient" -set <new_password> true
--------------------------------------------------------------------------------
Thank you,
