Hi @b_ry,

@Erik has made an excellent video series about Supabase connections (including using External Users authentication): [Adalo x Supabase Integration](https://forum.adalo.com/t/adalo-x-supabase-integration/18653).  
You don’t need to use external users btw - it is possible just to connect tables. Works like a charm 🙂

Best,  
Victor.
