# Set up CAS server SSO

One of the available [authentication methods](/19/docs/available-authentication-methods) for Totara is **CAS server (SSO)**. To set up CAS for authentication, follow these steps:

1. Go to *Quick-access menu > Plugins > Authentication > Manage authentication.*
2. Click the closed eye icon (![eye_close](https://cdn.document360.io/a007399b-031e-436b-999a-528240e16f58/Images/Documentation/eye_close.png?sv=2026-02-06&spr=https&st=2026-11-01T13%3A47%3A32Z&se=2026-11-01T14%3A47%3A32Z&sr=c&sp=r&sig=mNKjSxuEJzk418tege7jWx3se7mqBRv2hDhQbePu6%2Bo%3D)) next to the **CAS server (SSO)** authentication method. When the eye icon is open, the authentication method is enabled.
3. Click **Settings** next to **CAS server (SSO)** to configure the plugin settings.
4. Click **Save changes**.

As CAS is an external open source solution, you can read more about [how CAS works on their website](https://www.apereo.org/projects/cas).
