+Amazon Cognito creates a user group for each OIDC, SAMl, and social [identity provider](./cognito-user-pools-identity-federation.html#cognito-user-pools-identity-federation-how-it-works) (IdP) that you add to your user pool. The name of the group is in the format `[user pool ID]_[IdP name]`, for example `us-east-1_EXAMPLE_MYSSO` or `us-east-1_EXAMPLE_Google`. Each unique automatically-generated IdP user profile is automatically added to this group. [Linked users](./cognito-user-pools-identity-federation-consolidate-users.html) aren't automatically added to this group, but you can add their profiles to the group in a separate process.
