Where to change your username in the miHoYo account settings
You change your Genshin Impact username through the miHoYo account website, not inside the game itself. The game displays your username, but the actual change happens in your account settings at account.mihoyo.com.
Log in with the email or phone number tied to your miHoYo account. Once you are logged in, look for "Account" or "Settings" in the left menu — the exact wording depends on your region, but it is always the first section after you log in. Click it, then find "Username" in the list of fields you can edit.
Your current username appears in a text box. Delete it, type your new username, and click the save or confirm button below. The change takes effect when ready, though it may take a few minutes to show in the game client if you are already logged in.
Key Takeaways
- You must change your username on the miHoYo website at account.mihoyo.com, not in the Genshin Impact game itself.
- Usernames can be 3 to 20 characters long and can include letters, numbers, hyphens, and underscores, but not spaces or special characters.
- You can change your username once every 30 days, so choose carefully before you save.
- The change shows up in the game within a few minutes, but other players may see your old name briefly if they have not refreshed their friend list.
Username rules and what characters are allowed
miHoYo enforces specific rules on what you can use as a username. Your username must be between 3 and 20 characters long. You can use uppercase and lowercase letters, numbers, hyphens, and underscores. You cannot use spaces, periods, or special characters like @, #, $, or &.
The username cannot be blank, and it cannot be the same as your current one — the system will reject it if you try to save without changing anything. Avoid usernames that mimic official miHoYo staff or famous players, as the system may flag these as impersonation attempts and prevent you from saving.
The 30-day waiting period between changes
After you change your username, you must wait 30 days before you can change it again. This is a hard limit — there is no way to change it sooner, even if you contact miHoYo support. Plan your new username carefully before you save, because you will be stuck with it for a month.
If you make a mistake and realize you hate your new username five minutes after changing it, you still have to wait the full 30 days. Write down the date you changed it so you know when you are may be able to access to change again.
What happens to your username in the game and with other players
Once you save your new username on the miHoYo website, it appears in Genshin Impact within a few minutes. Your profile, your signature, and your name in co-op domains all update to show the new username. Your player ID — the number that never changes — stays the same, so friends can still find you by that number if they have it saved.
Other players who have you on their friend list may see your old username for a while because their game client has not refreshed yet. They will see the new name the next time they restart the game or manually refresh their friend list. This is not a problem — it just means there is a brief delay before everyone sees the change.
Troubleshooting: username change not saving
If you click save and the page does not change or shows an error message, check that your new username follows the rules: 3 to 20 characters, letters and numbers only, no spaces or special characters. If it does follow the rules and still will not save, try logging out of the miHoYo website completely, closing your browser, and logging back in.
If the error message says "Username already taken", someone else has claimed that name. Choose a different one. If the error says "You can only change your username once every 30 days", you have already changed it recently and must wait until the 30-day window passes. Check the date you last changed it to confirm when you are may be able to access again.
Changing your username on different miHoYo regions
miHoYo runs separate account systems for different regions: Global (most of the world), China, and a few other territories. Your username is tied to the specific region account you are using. If you play on both Global and China servers, you have separate usernames for each one, and you change them independently.
Log into the account website for the region you want to change. For Global, use account.mihoyo.com. For China, use account.mihoyo.com but make sure you are in the China section — the interface will be in Chinese. Change the username in that region's settings, and it affects only that region's game client.
Frequently Asked Questions
Can I change my username back to what it was before?
Yes, but only after 30 days have passed since your last change. You can change to any username that follows the rules, including one you used in the past. However, if someone else has claimed that old username in the meantime, you cannot use it.
Does changing my username affect my progress or adventure rank?
No. Your username is just a display name. Your adventure rank, characters, items, and all progress stay exactly the same. Your player ID never changes, so the game knows it is still you.
What if I see an error that says my username contains banned words?
miHoYo blocks usernames that contain profanity, slurs, or references to real-world violence or illegal activity. Choose a different username that does not include these words. If you believe your username was rejected by mistake, contact miHoYo support through the account website.
Can I change my username if my account is banned or suspended?
No. If your account is suspended or banned, you cannot access the account settings to change your username. You would need to contact miHoYo support to resolve the suspension first.
Will my friends still be able to find me after I change my username?
Yes. Your player ID stays the same, so anyone who has your ID saved can still find you. If they search for you by your old username, they will not find you, but if they search by your new username or your player ID, they will see your profile.
