Your Hushed username is the email address you first signed up on Hushed with (you can also see this displayed at the top of the 'App Settings' menu) 

Looking to change the email associated with your Hushed account? To do so, please follow these steps:

1️⃣ Go to 'App Settings' (Click gear icon on top right of the 'Main Menu' screen)
2️⃣ Select 'Account' 
3️⃣ Select 'Change Username/Email
4️⃣ Enter and confirm the email address to which you wish to change your account username!

If you are having any difficulty doing so, make sure you do not already have an account under that same username.
