KeePass. Putting your passwords on someone else’s webserver is just asking for trouble.

If I understand correctly, ‘Local’ is a feed with only posts that were made on the local server. So here on lemmy.world, that would contain only posts to communities hosted on lemmy.world. Whereas the ‘All’ feed brings in posts from other servers that lemmy.world knows about. So posts from lemmy.ml or beehaw.org will be included. It does seem to take a bit longer to populate the All feed though, and you’ll notice posts ‘pop’ in as you scroll.
