Agree on SSO, but even easier, to hit something like 80% of the business market you can just:

https://www.xsplit.com/user/auth?redirect_to=%2Fdashboard%2F...

This gives you anyone doing sign-on via Google Workspaces and anyone doing sign-on via O365/M365, as well as anyone using managed Apple IDs.

Zero SSO integration / support required.
