This release adds back the DRM check present in Prism Launcher that prevents users from adding an offline or authlib-injector account unless they first add a Microsoft account that owns Minecraft.
This DRM check was originally removed by PollyMC, but removing Prism Launcher's DRM is not one of Fjord Launcher's goals.
For now, you must provide your Microsoft client ID to use Fjord Launcher, and therefore the intended audience of Fjord Launcher is currently restricted to enthusiasts and developers. Follow these steps to obtain a client ID. Then, in Fjord Launcher, go to Settings -> APIs -> API Keys and enter the client ID under "Microsoft Authentication".
