Hi we are a web development company (Melbourne, Australia) currently using SugarCRM too. I have started to build a module for usernames/passwords too as we are long overdue for this functionality. I am about to deploy the first run which includes - FTP details, Domain Name Registrar Information, Server Details (for colocation clients), Other Passwords i.e. customer Paypal, Google and Social Media accounts etc (up to 4 extras). I have it set to hook into the Accounts Module. I am happy to share what I have to date (can easily set up a test instance)and to incorporate your needs into the module so we both get a good product out of it. Please let me know including what version of Sugar you are currently using and explain the level of access you want through the User Management area.
