# Authentication

Each workspace in Outline is connected to one more authentication providers, depending on which provider was used to create the workspace originally this may be email, Google, Microsoft, or Slack.

# Configuration

To setup and manage authentication providers, head to the **Settings → Authentication** screen as an admin. Here you can see the already connected authentication providers, disable them, and connect new ones. For example, you could switch from Google to Microsoft authentication.

# Security

Outline includes many configuration options to restrict and enable additional access to your Workspace. Navigate to **Settings → Security** to configure the following settings.

## Allow users to send invites

This setting allows any member with workspace access to invite additional team members. As this has billing effects it may be disabled, in which case only admins can send workspace invites.

## Require invites


:::info
**Note**: This option is only available in cloud and licensed editions

:::

By enabling this option new users must be invited to the Workspace before an account can be created. If you want to keep tight control over which of your team mates are able to login then it is recommended to enable this option.

If anyone that has access to your team’s SSO provider (eg Google Workspace) should be able to access Outline then this option can be disabled, this is usually the case.

## Default role

The default role in Outline is usually “Member”, you can change this to “Viewer” so that new users do not have any editing access unless explicitly upgraded by an admin. This option is useful if you are using Outline primarily as read-only reference.
