Manage the Default Administrator Account
When you install Hub for the first time, you set the username and password for the default administrator account. This account is assigned the System Admin role in the Global project.
If you forget the credentials for the default administrator account, or have inherited an installation that was configured by another administrator, you can reset the username and password for the account to their default values. You can also set the system properties for the default administrator when you restore the account.
You can also use this procedure when two-factor authentication is enabled and the default administrator no longer has access to the authentication app that is paired with the account. Resetting the default administrator account to its default state also disables two-factor authentication.
