MultiMC Linux support for Microsoft logins is... weird, which has been my reason for putting off the migration.
The MultiMC dev has since been hired as the official Minecraft launcher dev, and I guess that means they don't want to just be publishing their Microsoft SDK key for the Minecraft logins. But it means they've been on a bit of a war on linux distros packagng MultiMC or Linux users using anything other than his published binaries.
I've recently switched to GDLauncher, so will have to see how their MS account support story is, though it's got more of a "modern"/flat/big pictures UI feel to it and is clunkier to use
