Create customer, but he must later generate again a password - Why?

[DerJustin]

Hello community,

when i create a customer with subscribe in Plesk 12.5., then must later my customer via email the password again generate.
The password is not in the automatical email available. In Plesk 11.5 was it available and my customer must not generate a new password.
Can i it disable, so the password is in the email available and he must not generate a new or is it not possible?

Sorry for my english ^^

Sincerly,
Justin
