I personally prefer LastPass’s pronounceable passwords over this. But the problem about LP is that, besides inconvenient, it’s on the other hand of Bitwarden. But for now, XKPassword has been doing great for me so far.
I understand about the globalization problem. I’m not from US either. So far, I didn’t find people who did this into other languages. But I just use XKPassword and translate each word, so it gives me clues about what a passphrase can be.
It would be formidable to have this feature in Bitwarden, of course. But I guess this is minor priority for now. Let’s wait (a while) and see. ¯_(ツ)_/¯
