We can use the following methods to retrieve plesk Admin Password.

For Linux:

#cat /etc/psa/.psa.shadow

This will provide the current admin password in an un-encrypted form.

For Windows:

If we have RDP (Remote Desktop Protocol ) access to the windows server, we can use the plesksrvclient.exe utility located in %plesk_bin% folder to set up a new password or retrieve the old one.

We can retrieve the current password by running this utility with:

“%plesk_bin%plesksrvclient” -get

We can also set new admin password by running the following command:

“%plesk_bin%plesksrvclient” -set true
