Retrieve the rest of a line from a search

Question

I have a file with these lines :

BDD_USER=use
BDD_PASS=password

I would like to get the password beside BDD_PASS=

Currently i'm trying grep command to retrieve this from Linux shell.

Like : grep 'BBD_PASS='

But this return the entire line i don't find any switch to get only the password.
