Plesk password recovery

August 25th, 2008 — Linux, Plesk

If you forgot your admin password in Plesk, you’ll need to connect to your server with ssh and you can find the password in the file /etc/psa/.psa.shadow .

[root@apollo ~]# cat /etc/psa/.psa.shadow
<admin_pass>

To find mailbox’s password in Plesk, connect to your server with ssh, then use the following SQL query to reveal mailbox password (replace MAILBOX_NAME with your mailbox name):

[root@apollo ~]# mysql -u admin -p`cat /etc/psa/.psa.shadow` psa
[...]
mysql> SELECT m.mail_name, d.name, a.password FROM mail AS m LEFT JOIN (domains AS d, accounts AS a) \
ON (m.dom_id = d.id AND m.account_id = a.id) WHERE m.mail_name='MAILBOX_NAME'
