That would be do-able but not prefered.

And to be clear, the saving of credentials is saved in a SQLite database on your server, not in browser, not in anywhere else. Which would be seen as alot more safe than localStorage or similar.

appsettings.json would be similar but then its not possible to "hot-change" your backend settings through the UI.

I could possible write it like if there is values in appsettings.json then it doesnt use db saved credentials..
