@FCKGW,
I didn’t intend to close it, that is why it is now re-opened.
@lokan is correct about this though. The toggle you’re referring to is specific to extensions that require Google Authentication. It has nothing to do with having a Google “account” or anything like that.
If you want your Brave passwords in Chrome, you can export/import them manually as an HTML file, but there is no way to automate or “sync” them.
