@jsulmeyer,
I do apologize for the inconvenience there – as much as I hate to say it those PWs are gone it seems. Brave Sync only syncs bookmark data at this time, with passwords and other browsing data to follow.
There is a #PasswordImport flag that can be enabled but it looks like the feature doesn’t work in Brave or Chrome (looking into this feature in further detail). That said, I will open an issue to add this feature or, at the very least, investigate the flag mentioned above to see why it won’t function when enabled.
