I've used Brave for who knows how long now, and it's only been really recently (with the introduction of Brave Talk and Brave Search, which have paid pro tiers) that they've introduced accounts at all. There may be something related to signing up for a crypto wallet if you want to use those features (since at least turning the crypto into fiat requires the crypto exchange to "know their customer"). But the browser itself, the sync features etc., none of that needs an account. The sync service doesn't even have accounts, just a long string of words to serve as a the fingerprint for a sync chain.
