Hello,
is it safe to change the psa_root password?
I need to access the db with phpmyadmin in order to easily set the externalid of whmcs.
@Pier Paolo Ronzino
It is not required to change password for psa_root.
You could log into psa database using the command
psa db
And create the appropriate user for phpmyadmin. BTW, you could use pmpmyadmin provided by Plesk, it is automatically configured.
