This article covers how to change your Vercel username after registering. Your username functions as your URL namespace within Vercel (e.g. vercel.com/<username>).
Changing Your Username
In order to change your Vercel username, first navigate to your Vercel account settings page on the dashboard. Once you arrive at the correct fieldset, please enter in the input your new username.
NOTE: Please be aware that the account settings are different to project settings.
If the Vercel username change was successful, you will see a toast in the bottom right corner of the screen indicating that Your username has been updated.
