The Mobile Path to Renaming Your Account

You can change your Roblox username on a phone or tablet using the official Roblox app or a mobile browser, but the process differs slightly from desktop. The fastest route is the app itself — open it, go to your account settings, find the username option, and follow the prompts. If you use a browser instead, the steps are nearly identical, though the layout looks different on a small screen.

One thing to know upfront: Roblox charges 1,000 Robux for a username change (the in-game currency you buy with real money). You get one free rename when you first create your account, but after that, every change costs the same amount. The change takes effect when ready once you confirm it, and your old username becomes available for someone else to claim after a short delay.

Key Takeaways

  • Open the Roblox app on your phone, tap the three-line menu at the bottom right, and select Settings to find the username change option.
  • You need 1,000 Robux in your account balance to pay for the rename — you cannot use Roblox Premium or gift cards to cover it.
  • The change happens when ready, but your old username becomes available to others after a few minutes.
  • If you use a mobile browser instead of the app, sign in, tap your profile icon, go to Account Settings, and look for the username section.

Changing Your Username in the Roblox App

Launch the Roblox app on your phone or tablet. At the bottom of the screen, you will see a menu bar with five icons. Tap the three horizontal lines on the far right — this opens your account menu.

Scroll down until you see Settings and tap it. Inside Settings, look for Account or Account Info depending on your device. Tap that section. You should now see a field labeled Username with your current name displayed. Tap on that field to edit it.

Type your new username into the box. Roblox will tell you when ready if the name is already taken or if it breaks the naming rules (no special characters, no spaces, between 3 and 20 characters). Once you see a green checkmark or confirmation that the name is available, look for a button labeled Change Username or Confirm. Tap it.

The app will ask you to confirm that you want to spend 1,000 Robux. Make sure your account has that balance — you can check by looking at the Robux counter at the top of the app. If you do not have enough, you will need to buy more Robux before proceeding. Once you confirm the purchase, the change is final and when ready.

Changing Your Username in a Mobile Browser

If you prefer to use Safari, Chrome, or another browser on your phone, open it and go to roblox.com. Sign in with your username and password. Tap your profile icon — it is usually a small circle or avatar image in the top right corner of the screen.

A dropdown menu will appear. Look for Settings or Account Settings and tap it. On the settings page, find the section labeled Account or Account Info. Inside that section, you should see your username displayed. Tap on it to edit.

Enter your new username and check that it is available — Roblox shows you this in real time. When you are ready, tap the button to confirm the change. The browser will prompt you to confirm the 1,000 Robux charge. Verify that you have enough Robux in your balance, then complete the transaction. The change takes effect right away.

What Happens If You Do Not Have Enough Robux

If your account balance is below 1,000 Robux, you cannot complete the username change until you buy more. The app or browser will show you how many Robux you need and give you the option to purchase them. Tap that option and follow the payment steps — you can buy Robux using a credit card, gift card, or other payment method your account supports.

Once the purchase goes through, your Robux balance updates within a few seconds. Return to the username change screen and try again. This time you should have enough to complete the rename.

Recovering Your Old Username If You Change Your Mind

If you change your username and when ready regret it, you cannot undo the change directly. However, your old username does not become available to others right away — there is a grace period of a few minutes to a few hours depending on Roblox's system. If you want to reclaim your old name, you can pay another 1,000 Robux to change back to it during this window.

After the grace period ends, your old username is open for anyone to claim. If someone else takes it, you cannot get it back. For this reason, think carefully about your new name before confirming the change.

Troubleshooting Common Mobile Issues

If the Settings option does not appear in your menu, try closing the app completely and reopening it. Sometimes the menu does not load fully on the first try. On Android, you can do this by swiping the app away in your recent apps list. On iPhone, swipe up from the bottom of the screen to close it.

If you see an error message saying the username is unavailable even though you typed it correctly, the name may have been claimed by someone else between the time you checked and the time you tried to confirm. Go back and choose a different name.

If the payment fails when you try to confirm the Robux charge, check that your payment method is valid and that your account has permission to make purchases. If you are under 18, a parent or guardian may need to approve the transaction. Try again after a few minutes — sometimes payment systems need time to process.

Frequently Asked Questions

Can I change my username for free on mobile?

You get one free username change when you first create your account, regardless of whether you use mobile or desktop. After that, every change costs 1,000 Robux. There is no way around this fee on any platform.

How long does it take for my new username to show up?

The change is when ready. Your new username appears in your profile and in games when ready after you confirm the purchase. Other players will see your new name right away.

What if someone else takes my old username?

Once the grace period ends (usually a few minutes to a few hours), your old username becomes available to anyone. If someone claims it, you cannot reclaim it unless they change their own username later. Plan ahead if your old name is important to you.

Can I use spaces or special characters in my new username?

No. Roblox usernames can only contain letters, numbers, and underscores. Spaces, hyphens, periods, and other special characters are not allowed. If you try to use them, Roblox will reject the name and ask you to choose a different one.

Do I need Roblox Premium to change my username on mobile?

No. Roblox Premium does not give you a discount or free username changes. You need 1,000 Robux in your account balance, whether or not you have a Premium membership.
