As the admin user of your Soapbox instance you enjoy extraordinary powers. To ensure these powers are safeguarded we highly recommend you enable two-factor authentication.
Go to Settings > Security > *Configure MFA to enable two-factor authentication.
You probably want to familiarize yourself with Soapbox before you start accepting new users. With this in mind we recommend you temporarily disable new user registrations.
Go to Dashboard > Registration and select Closed for now. You can re-enable it later.
