I mean, pretending to be someone in another instance, “stealing” the username, is trivial. I see the more likely targets being instance admins or high profile users. Should we worry somewhat about this?

    Yes, for sure. While the identity of a user can be checked, nobody is going to do this every time. IMO the simplest solution would be to just always show the instance even if a display name is set.

        It currently shows: pic, username (or login name@instance), local link to the comment, federated link, language

        Seems like the easiest solution would be to always show the user’s instance in a separated column

        I feel like they could solve it by adding instance only when another user with similar name is present in the comment section. It would make it clear that a duplicate username is present without changing a lot for a majority of lemmy-commenr sections.

    That’s why instance is part of the username. It’s no different than email addresses.

      Setting a display name hides the instance bit. You have to check the URL or profile to see which instance they’re on, which people definitely won’t do every time. Especially if an impersonator just joins inside a thread mid-conversation, it won’t be obvious at all that it’s suddenly a different person writing.

        Just like emails, when people write something like ”Amazon Gift Cards” <yolo@yolo.com> in the From field.

      His concern is probably that in comments etc. only username is displayed. You have to go to person’s profile to discover their instance.

    Some other projects in the fediverse have a verification mechanism in place.

    I personally like Mastodon’s: if you add on your profile a link to a webpage that itself links to your profile, Mastodon will show a green checkmark next to the link: https://joinmastodon.org/verification

    So you can verify your profile by linking to a webpage you own or testifies your account’s authenticity (ie. your blog, your author page of the publication your write for, etc.)

    Hopefully other projects (including Lemmy) will take inspiration from this process to limit impersonations.

    It’s a bit of a problem, indeed. Check my current display name as an example - I’m writing from a lemmy.ml account, but the display name impersonates another account in another instance (beehaw.org). Granted, both accs are owned by the same user, but nothing prevents me from doing it towards someone else’s account.

    Based on that, I think that:

    • the Lemmy software should not allow you to use “@” as part of your display name. Ever.
    • clients should always show which instance you’re from, even with a display name. (A simple icon would be fine.)
    • two accounts in the same instance should never be allowed to use the same display name.

    And for us, users: never rely on the display name. If the identity of someone is contextually relevant, always check the actual username, not the display name.

      Twitter implementation seems good enough. Big display name with smaller unique handle below. Might be a bit bloat, but solves the problem.

    It’s something we should be worried about everywhere we go online.

    So try having at least 3 different passwords for personal accounts/websites and also contact moderators or support if you suspect your account has been compromised.

      That’s an awful take. Grab a password manager and have a random password for every single account of yours. That way all you have to do is remember a single strong password and that’s it. Instead of playing Russian roulette when one service you use gets hacked and someone gets a hold of your username / email and one of your 3 different passwords…

      This isn’t about compromised accounts though. I could just create an account, give it the display name “Granixo” and your profile picture. It would look exactly like your account unless people actually click the profile or look at the profile URL.

      That’s terrible advice when password managers are a thing. Also, this is about impersonation, not credential theft.
