It’s fairly clunky. The developer is a nice guy and responds really quickly, but files sometimes didn’t sync and I got an error twice where it just didn’t sync anymore.

There also isn’t a proper setup guide or documentation (but you can always add the help flag halfway through your jar usage to know what parameters you’re missing). The developer has been kind enough to help me through that though.

It might just be a skill issue on my end of course. Though needless to say I moved back to something else after a couple of months (In my case to Seafile)

Also its Dutch translation is acceptable (I did that)

At the very least you’re misguided or don’t know what you’re talking about. Passkeys are not vendor locked in and of themselves.

You can make the same argument against password managers because most iPhone users that use them, use Apple’s one.

Personally I’m more than happy to cover the Dutch translation if you have the time to get translations working. Thanks for the project!
