I was under the assumption that I can use one fediverse account across all ther fediverse apps, but this doesn’t seem to be the case.
I.e. I downloaded the mastodon android app and tried to select kbin.social as the server, but it gives an error.
Same for jerboa, it won’t let me connect to kbin.social, saying invalid credentials.
Is this something on the roadmap or am I simply wrong with my assumption?
There is no options yet for Single Sign On in the Fedverse as there is no one single instance/platform to rule them all. You sign on to your instance and through that you can visit other Fedverse instances/communities by searching from within your instance. Right now since Lemmy and Kbin and it’s associated apps are so young the ability to visit other Fedverse platforms is not yet fully available so the abilities of your instance may be limited.
