Last.fm lets you change your username once, and the change is permanent
Last.fm allows you to change your username, but only one time. Once you make the change, you cannot change it back or pick a different one later. The old username becomes available for other users to claim after a waiting period. Before you change it, make sure the new name is exactly what you want — there is no undo.
The change takes effect when ready across your profile, listening history, and all connected apps. Any links to your old profile will stop working, so if you have shared your Last.fm URL anywhere, those links will break.
Key Takeaways
- You can change your Last.fm username only once, and the change is permanent with no way to revert it.
- The username change happens in your account settings under "Change Username" and takes effect right away.
- Your old username becomes available for others to claim after a set period, so choose your new name carefully.
- Any public links to your old profile will no longer work after the change, including shared URLs and embedded widgets.
- You must wait at least 30 days from account creation before you can change your username.
Where to find the username change option
Log into your Last.fm account on the website. Click your profile icon or username in the top right corner and select "Settings" from the dropdown menu. On the Settings page, look for the "Change Username" option — it is usually in the main account settings section, not buried in a submenu.
Click "Change Username" and you will see a text field where you can enter your new name. Last.fm will tell you right away if the name is already taken or if it breaks their username rules. Usernames can contain letters, numbers, hyphens, and underscores, but not spaces or special characters.
Requirements and restrictions on new usernames
Your new username must be between 2 and 30 characters long. Last.fm does not allow spaces, and most special characters are blocked — stick to letters, numbers, underscores, and hyphens. The system will reject names that are already in use or that violate their content policy.
You cannot change your username if your account is less than 30 days old. If you created your account recently and the option is grayed out, wait until the 30-day mark has passed. Last.fm also requires that your account be in good standing — if your account has been suspended or flagged for violations, you may not be able to change your username until the issue is resolved.
What happens to your old username after the change
Your old username does not disappear when ready. Last.fm holds it for a waiting period before releasing it back into circulation. During this time, the old username is not available for anyone else to use. After the waiting period ends — typically 30 days, though Last.fm does not always publish the exact timeframe — the old name becomes available for new users to claim.
This means if you change your username and later regret it, you cannot straightforward change it back to the original name. Someone else may have already claimed it. Plan your new username carefully, because your only option to go back is to contact Last.fm support and explain the situation, which they may or may not honor.
How the change affects your profile and data
Your listening history, scrobbles (tracked plays), and all your music data stay with your account. The change is cosmetic — it only affects the name displayed on your profile and in the Last.fm community. Your friends list, followers, and any playlists you have created remain intact.
However, any URL that pointed to your old profile will break. If you shared a link like "last.fm/user/oldusername" with friends or embedded it on a website, that link will no longer work after the change. You will need to update those links manually to point to your new username. Some third-party apps that connect to Last.fm may also need you to re-authenticate or update your username in their settings.
Changing your username on mobile apps
The official Last.fm mobile app does not have a built-in option to change your username. You must go through the Last.fm website on a computer or mobile browser to make the change. Log in at last.fm, go to Settings, and follow the steps above.
After you change your username on the website, the mobile app will update automatically the next time you log in or refresh your profile. If the app still shows your old username after a few hours, try logging out and logging back in to force a refresh.
What to do if you cannot find the change username option
If the "Change Username" option is missing from your Settings page, check whether your account meets the requirements. Your account must be at least 30 days old, and it must be in good standing with no active suspensions or violations. If you are below the 30-day threshold, the option will not appear.
If your account is old enough and the option is still not there, contact Last.fm support through their help page. Explain that you cannot see the username change option and provide your current username and account email. Support can tell you whether there is a restriction on your account or if there is a technical issue preventing the option from showing.
Frequently Asked Questions
Can I change my username back to my old one after I change it?
Not directly. Once you change your username, you can only change it one more time if Last.fm allows it, but you cannot change it back to the original name unless it has not been claimed by someone else. Your best option is to contact Last.fm support and explain the situation, though they do not may provide they will restore your old username.
What happens to my scrobbles and listening history when I change my username?
Your scrobbles and listening history stay with your account. The username change does not affect any of your data — it only changes the name displayed on your profile. All your tracked plays, charts, and statistics remain exactly the same.
Do I need to change my username on connected apps like Spotify or Discord?
No. Apps that connect to Last.fm pull your information from your Last.fm account, so they will automatically show your new username once you change it. You do not need to update anything in those apps unless they require you to re-authenticate your Last.fm account.
How long does it take for my new username to show up everywhere?
The change takes effect when ready on the Last.fm website and in your profile. Connected apps and third-party services may take a few hours to update, depending on how often they sync with Last.fm. If an app still shows your old username after a day, try logging out and logging back in.
Can I use special characters or spaces in my new username?
No. Last.fm usernames can only contain letters, numbers, hyphens, and underscores. Spaces and special characters like @, #, !, or periods are not allowed. If you try to use them, Last.fm will reject the username and ask you to choose a different one.
