UI Idea for one-click Lemmy account migration

  I think UI is the least of their worries. They’ve not even decided what to migrate yet.

    It really needs to be everything - posts, comments, subscriptions, upvotes/downvotes, blocks, and mod status. It needs to be such that signing in to your account on the new instance is the same as signing into on the old one. It should be so seamless that you can just switch instances just to try out a new one and switch back again if it isn’t for you.

      It won’t be anything even close.

      Indexes are unique to each instance. Post ID, Comment ID, Vote ID. There’s no way to correlate this information between two instances other than to do a full text match, post by post, comment by comment, vote by vote, to determine if what is being imported or “new”.

      Even if you go that router, then there’s the quandaries that follow… if you import what is effectively a “new” post to your new instance, do the comments (which aren’t yours) come along, or do you simply end up importing your post with no interaction history.

      That’s just off the top of my head.

      If you’re lucky you’ll get to keep your cake day.

      It’s not that on mastodon and it shouldn’t be that here either. There needs to be some consequence to switching instance.

  There’s two problems with this.

  A. You’re now allowing people to hop, and even name change. Let’s say they’ll allow that.

  B. You’re missing the password. Every instance should have a unique salt, passwords should NEVER be reversible, and never be stored insecurely (AKA before salting the hash for instance). I use a different password for every site, but I’ve had sites tell me “Your password is X” … holy shit that’s a HUGE security flaw for multiple reasons.

  So if I’m migrating and don’t need to set a new password, that’d be questionable.

  C. This can be done unscrupulously. If I get control of someone’s account, I can migrate it and essentially steal all their accounts.

    A. If you want to hop you can already just create a new account. What’s the issue with taking ownership of your posts with you?

    B. Just migrate the salt, too. A server can have per-user salts, which may be migrated together with the hash.

    C. If you already have control over someone else’s account, what additional benefit does migrating serve?

      A server can have per-user salts, which may be migrated together with the hash.

      They better have per-user salt. Otherwise that would defeat the entire purpose of salt, which is to make sure that it isn’t obvious if two users have the same password.

      What’s the issue with taking ownership of your posts with you?

      I think the question is will they allow it. Though I’m sure there’s weird edge cases. I’m not an expert on the Ferdiverse, but let’s say you hope from Lemmy.world to Threads or something like that. But Lemmy.ca banned threads, now your posts have moved. It kind of creates a weird migration.

      Though the counter argument also exists “Why do you need to take ownership of posts?” I don’t know if that’s as valuable to go through the hassle. If anything moderator positions is what would matter more and can be done through a process rather than migration. (promote B, remove A)

      But like I said, I’m not an expert so I’m still learning.

      B. Just migrate the salt, too. A server can have per-user salts, which may be migrated together with the hash.

      If ever server has per-user salts, great. But that’s again a question for implementation. You’re making a huge assumption that’s how it works, and there’s no server dependent values. I mean even the hashing algorithm should be able to be proprietary be different between servers (At least that’s how I’d do it).

      C. If you already have control over someone else’s account, what additional benefit does migrating serve?

      Because control can be reverted, or limited. I mean if I can step to Bieber’s laptop when he’s in the bathroom, that’s not the same as having his login in and password… If lemmy.world sees someone has broken in and locks the account, or Bieber changes his password, your access is lost, where as if you migrate it, can lemmy.world revoke the migration? And if that’s the case, doesn’t that create some strange problems?

      I’m not saying this is a bad idea, but I think you have to think more about the edge cases.

  They might just go Masto-style migration and just but a banner on your profile linking to your new account, and give you a list of communities to import.

    @cheerjoy I think in the long-run of the Fediverse it would be better if we can fully export all of our data to a new instance sure maybe still have a redirect account on the original instance you where using but it would be good for not only people that want to move instance to another popular instance but also if someone creates there own allowing you to try out the Fediverse before spending the time running your own instance as apart of it.

  I discovered this a couple of days ago: github.com/CMahaff/lasim. It just transfers your subscriptions to your new account in another instance. I don’t really mind not being able to transfer comments for now, but this has been very very helpful when I moved my subscriptions from one of my lemmy.world accounts to another instance because of the recent downtimes.

  I think migration should just do all of the non-public stuff, like subscribed+blocked communities and saved posts

  Let’s just be honest the default interface sucks and should be used only for account creation
