Can i use Power BI Embedded with my own user authentication database

I developed my own user database that I integrated with my Customer-Facing Web Portal. Each customer has a login/password that is stored in my own user db.

I Would like to know if can i use the Power BI embedded to embed a dashboard in my Web Portal and use Row Level Security to restrict access to some data based on User or another attribute (like "COMPANYNAME")?

Thanks!
