Is there no way to authenticate an Avalonia app without adding a back end?

[Enter feedback here] Alot of tutorials I find for other application types suggest just adding an App registration in Entra, copy and pasting an APP ID and maybe a Tenant then getting the benefits of SSO. However those tutorials seem to use methods that are platform specific or are old. This being the only Avalonia guide I can find on the internet the first thing they have us do is make a "backend". Which requires signing up for a new subscription in azure (12 months free) then starting a database and app registration in that subscription instead. When following the tutorial I got constant errors just trying to run "azd up" because the region was full or now myself being throttled with too many recreate attempts. Is any of this even necessary? or is there another way to do simple authorization that doesn't involve spinning up a Azure Subscription? --- #### Document Details ⚠ *Do not edit this section.
