As per this article: https://proconnect.intuit.com/community/help-articles/help/role-management-via-my-account/00/4212 "Beginning in Tax Year 2016, industry wide standards established through the IRS Security Summit require professional tax software vendors, including Intuit, to validate each individual user's identity. In compliance with these changes, Intuit ProConnect Lacerte requires all users to login and be authenticated as a valid user of your firm before the Lacerte software will open."

The purpose of the password is to protect you and your clients and so I would not recommend a program or tool to remember that for you as you are making yourself vulnerable and bypassing the security put in place to protect you and your clients.
