User management through UI with a SQLite DB

**is your feature request related to a problem? Please describe.**

I have some less technical users and I want them to be able to reset their own password.

**Describe the idea / solution you'd like**

User management through the UI, with self-serve password reset and signup, ideally with just a simple sqlite DB for simplicity.

**Describe any alternatives you've considered**

Using something like Keycloak and `forward_auth` for SSO but I don't think that would work here either and is a very heavyweight solution.
