is it possible to use jerboa as a kbin client? where it says add account can I add my kbin account?

It's not a dumb question, but it's not going to work. The APIs are really different:

• https://docs.kbin.pub/#introduction
• https://join-lemmy.org/api/classes/LemmyHttp.html

Although kbin and lemmy mostly share a federation protocol, they're different applications with different client-access APIs, apps for one definitely won't work with the other. I believe the only app for kbin is https://github.com/ernestwisniewski/kbin-mobile.

It's worth a try, but I doubt it would work. Kbin might have a different authentication flow so it won't work with any of the Lemmy apps.

Even if the auth flow worked, unless the APIs are exactly the same, then it won't work as expected anyway :)

I tried logging in with a kbin instance and it didn't work.
