you don't have to do jack to achieve that with brave sync, syncing your password db, that is, just enable it, done
i will only say that one time i think somehow something breached that as i had data manipulated in that password DB, or something, i forget now... suffice it to say i don't think it's perfect but it's hella better than bitwarden, even still, for UX and for simplicity and for its setup difficulty and complexity to operate
the root problem is always, and ever, about the fact that the internet incumbency is not going to let everyone put everything on the internet, and the reason being that almost everything that might do this is vulnerable, it would be armageddon, but never mind that these assholes should learn some fucking opsec and, you know, implement that as best practices in code
until that multiple layered bullshit is finally broken, give me brave sync over bitwarden any day
honestly i just want an NFC/USB based simple physical token with signing capability inside it and extensible, and high enough spec to actually do cryptographic shit
all this other shit is just makeshifts while fiat clown world IT industry finally comes to grips with their actual customers business
and even there, ffs social media customers are not the users, etc etc .... adlib to fade
