Gravity comes with a user management dashboard (that you created during the installation process) that enables you to view and manage the accounts and users within your application. No more database diving, yay!
Here you can:
Edit user or account details
To access your dashboard, enter your domain followed by /master then sign in with the credentials you created during setup.
You can log in as any user via the users screen in your master dashboard. Simply click the login icon in the user table and you'll be authenticated and redirected.
