When you first begin Diner DASH Adventures, you'll be asked to create a unique Username. This is tied to your account and can be used to locate your account in case you somehow lose it. 
 
Make sure it’s a memorable one!
 
If you don’t remember your username, we won’t be able to help you recover your account as we won’t be able to locate it.
 
Take a screenshot of your username and Player ID, just in case!
 
You can locate both by tapping on the Gear icon and accessing your Settings. It will appear in the section that says Set Username once you have chosen a username,
