There is no login feature for Brave and there wont be one in future as well. For bookmarks we are implementing Sync which works with other Brave browsers on desktop/iOS/Android. In future iterations sync would also support history and site settings and possibly passwrods. But at no point will you ever have to login to use any of these features.
Hope this helps. The Google features you mentioned are not going to be part of Brave as the application model is very different.
