The cross-platform Password Store is a good match for Brave.
It works on most (all?) platforms supported by Brave: GNU+Linux, MS Windows, OS/X, iOS, Android, etc.
I see that https://github.com/brave/browser-laptop has now gained a request for Password Store. This leaves the other platforms unaddressed, I think.
Please enable Password Store, on all platforms Brave supports, as a system for storing and retrieving website credentials.
