Trinity has the option to have multiple 'accounts' within the app. This allows you to have multiple accounts much like a banking app.
During setup, select a name for the account so you can identify it:
The standard name is “Main Account”
Each account represents a different seed. So whenever you create a new account be sure to follow the correct backup procedures.
You can rename each account in the Settings tab. A descriptive account name helps you remember the purpose of the account.
