Can I make my own members by a custom member database NOT by wix member

Hi,

I have a website and I’ve know everything about WIX member.

But,

I wonder if I could connect my member database because I have a firebase account and made an app and I want to let the visitors to login in the both of the app and website

What I want to say is :

Is possible to connect my member database to my website ?

Thanks for your fast respond
