Authentication of users¶
Sequel security service offers different mechanism or authentication providers to authenticate a user:

- Federation gateway. One of the features provided by Duende IdentityServer is the federation gateway; allowing our security service to act as a gateway to other external identity providers:

Configuring authentication providers¶
Authentication providers are configured at appsettings.json file at LoginSettings.IdentityProvidersSettings. Each provider has specific settings but all of them has an Enabled property to activate or deactivate it.
