Clubhouse encourages users to use their legal name and a simple username, rather than a catchy Twitter handle or creative IGN, which is possible on most platforms.
How do I change my name on the Clubhouse app? Reset username on Clubhouse 2021
So much so that name changing is a serious topic within Clubhouse – something you’ll quickly realise once you finally gain access to Clubhouse’s gated community. Below, we’ll explain how to change your name on Clubhouse – whether it’s your Clubhouse username or your legal name in the Clubhouse database.
WARNING: Users should be aware that they are only allowed to change their name on Clubhouse "occasionally." Clubhouse states "there is a limit to how often you can update your name" on its support page, meaning that you will no longer be able to change your name if you have recently changed it.
The same rules apply when you try to change your maker alias or username, but for the latter, the app notes that you can always change it later when you open the “Change your username?” screen on Clubhouse.
