Steps to change your Chess.com username
Web
Click 'Settings' from the menu in the bottom-left corner of any page on Chess.com
In your profile settings, click 'Change' next to your username
Enter your desired username and your password
If you registered with a social account like Google, Apple, or Facebook, you won't be asked for a password to complete the change. But if you do, simply setup a password first with the Change Password and then try to change the username.
Click 'Save' to apply the changes.
If the username you want is taken by an inactive account, you may request it from our Support team. Check out this article to learn the requirements: How do I request an inactive username?
Mobile
The option to change your username is currently only available on the Chess.com iOS app.
The following steps apply to users who registered with an email and password, as well as those who signed up using a social account.
Tap 'More' at the bottom right corner of your screen and select 'Profile'
From your profile screen, tap on the three dots in the upper right corner of your screen
From your profile settings, tap on the arrow next to your username
Enter your new username and select 'Continue'
If the username you entered is valid, you will get a confirmation box. Tap 'Yes' to apply your changes.
Please choose carefully. Members can only change their username once every 90 days!
Important to remember
Your username must be at least 3 characters long. It can only include letters, numbers, underscores, and dashes. It must start and end with a letter or number. Spaces are not allowed.
You cannot change your username if you are in a Live Chess game in another window.
If the username is taken, a notice will say it is unavailable.
