Perhaps you talked out your Brave browser being in sync or something like that as seen in
this post. So what he is saying is based on that.
this is also why i wasn't so happy to explain how I think they got into my and waited with it as long possible
i knew that there will be many unneeded questions and despite i have written that I think they wasn't able to breach my password manager password (because is truly strong 16 signs with special once) only login to Bitcointalk account using synced brave browser, browsing histor and autofill passwords
stated few times that only my Bitcointalk account was stolen
But in general the whole Idea of browser based password managers is just bad news. Avoid them at all costs if you can.
sure you are correct and thios is why all important or $$$ valuable accounts are always with 2FA anyways
somehow I missed Bitcointalk account but all of this is rather secondary topic
password managers like dashlane, keeper and others are also not the best idea despite better then generic manager i know, there is no good solution for that and i think that 2FA saved my day
