Local Authentication
Local authentication is the default until you configure an external authentication provider. Rancher stores user account information, such as usernames and passwords, locally. By default, the admin user that logs in to Rancher for the first time is a local user.
Adding Local Users
Regardless of whether you use external authentication, you should create a few local authentication users so that you can continue using Rancher if your external authentication service encounters issues.
From the Global view, select Users from the navigation bar.
Click Add User. Then complete the Add User form. Click Create when you're done.
