Does changing username affect progress?
I'm scared that when I change my MC username, all my progress and servers will be lost.
Is this what will happen?
Best Answer
No, you won't. Players are tracked with a unique ID, instead of your username as of Minecraft 1.7.10. You can only change your username every 30 days, and if someone changes their username, you cannot change it to their username for 37 days. As for servers, you'll have to ask the server owner, but you usually don't lose progress. https://help.mojang.com/customer/portal/articles/928638-minecraft-usernames

What happens if you change your username in Minecraft?
When you change your username, your previous name is saved for 37 days. This gives you an additional week to change back if you change your mind before your previous username becomes available to anyone else.Does changing your Minecraft username affect servers?
You can change your name as much as you'd like, it will not affect anything Mineplex related.Do I have to wait 30 days to change my Minecraft username?
They actually tell you here in the article, "In an effort to keep users from changing their names constantly, Mojang enforces a mandatory 30 day waiting period between name changes. This means that once you change your name, you'll have to wait at least 30 days before you can do it again."How long does it take for Minecraft username to update?
When you change you username, you have a 30 day cooldown before you can change your name again (so be sure you pick a name you like). Once you change your name, you are given 37 days (the cooldown plus a week) to revert back to your old name, before the old name is made available to other players.Every Game Affected By PSN ID Changes

Answer 2
in vanilla minecraft (neither plugins nor mods), you won't have any problems. in the case of plugins it depends on the server, so you might want to ask there. in the case of mods, some are known to store data in relation to your username (the first thing coming to my mind is extra utilities death inventory backup, although that's nothing you'd really care about on the average server. thaumcraft did the same with its research in 1.6, but i'm not sure whether that's still the case).
Answer 3
You will not lose any of your single-player worlds, or any of the servers on your server list. Your progress on servers will vary from server to server.
Plain survival servers should be fine, as most things in Minecraft use your UUID now rather than name. Most modded servers should also be fine, as the majority of mods have moved to using the UUID system rather than name, though you may want to ask a server admin.
The main server type that you are likely to lose progress on is vanilla servers with command blocks. Mojang hasn't added UUID support for scoreboards, so you may lose points, kills, or whatever else is kept in scoreboards.
Answer 4
It depends. Most mods and plugins have been retrofitted to use the UUID system (unaffected by username). Some mods might still use the username system, in that case, yes. You will lose data.
