QB DOES NOT save the password once the QB session is closed... I have tried with all the suggestions and offerings in user forums.

QB DOES NOT SAVE GMAIL PASSWORDS after closing your QB session.., It DOES connects to gmail and passes the google generated password (which us a long password lower case and frustrates every user I have chatted with).  When they log out of the QB session (which they do for security reasons) and log back in  QB Desktop... it requires them to re-enter the google generated password before they can send an invoice... This infuriates the users!  You surely can find a way to encrypt and save the passwords if you choose to do so.  Come on now! Listen to the Users!
