Great UX feedback, that's going to be sorted out in the next release.
Also the pipx comment made me decide to put much more thought into how sqlit helps with package installation on runtime, and I'm going to suggest pipx by default and it's also going to give the correct commands for every popular package manager.
I am going to implement the option to leave the password blank, so you'll get prompted for a password on connection every time, so nothing will get stored.
In the next release I am going to use Keyring to store credentials on the operating system's credential store. Stay tuned :)
I'm looking into indexes/triggers/sequences. That will be added in a near-future release, I hope you can benefit from it once I release it :)
