Why can you never change your username in Mastodon, Lemmy or Peertube? Is it a condition introduced by ActivityPub or a forgotten feature?
You must log in or register to comment.
You can change your display name but your user handle is fixed.
I imagine being able to change your user handle could cause issues with federation. If you changed your user handle, your instance would have to notify all other instances. If one instance didn’t get this information, your account before and after the change would look like two separate accounts on that instance.
You’re pretty much asking “why can’t I change my email”
You can make a new one if you want.

And what’s wrong with asking that? Plenty of email platforms let you change your primary SMTP address and/or add/remove aliases.
It’s a legitimate question. And it could be that the lack of ability to change it has a perfectly logical answer. It still wouldn’t invalidate the question.
You can migrate to a new account… this can achieve the same thing. It doesn’t always work as well as you’d wish though
Isn’t migration reliant on third party tools or your own effort to resubscribe and whatnot?
I migrated masto instances without complications, but some people have had a worse experience than I

I believe it’s not possible because it would untie the user from all of their comments and posts that seen on “any other website connected to the Fediverse”.
Only your instance can know who you are if you change your username but other instances couldn’t know that.
It’s really annoying that the unique identifier is the username and domain instead of an ID. My fiance switched her nationality and therefore her legal name, but there is no way to change it in PeerTube where I made an account for her. OK theoretically we can create a new account and change the ownership of each of her videos but there are hundreds of them.
Man, it seems so alien to me to use anything related to your legal identity as a username online.
I just put everyone’s first name there as the username for the whole family.
I wonder if it’s possible to batch-edit the database to auto-change ownership…
Probably, but I’d need to understand the database schema for it. Don’t really have time for that.
One thing I like about bluesky is that your identity doesn’t have to be tied to an instance domain - you’d still have issues if you want to change is later, but if you plan ahead and use your domain you can just move it between instances.
