Is your feature request related to a problem?

We use several Accounts colobrative and we have stored the electron app on a Netshare, but every User must configure the Accounts by himselves.
Also we have to enter the password every time we reopen the app.

Describe the solution you'd like

It would be nice to store the configuration for all users at once inside the Electron Folder. So we only need to configure it for all users.
Also it would be nice to have the capability to securely save the Password in the SQLite database

Describe alternatives you've considered

For a Workaround it would also be nice to import and export the configurations.
