How can post users’ passwords?

Hi,   Users log into my application via SSO (SAML module). I need to post the usernames and passwords to the service by using call rest action. Where can I access the password information of users logging in via SSO?

Passwords will likely be randomly generated (depending on your implementation) and stored as a hashed password. You're not supposed to be able to access their password information, that would be a huge security risk. Can you explain your use case a bit more?
