-## Authentik IdP
+NetBird works out of the box with popular Identity Providers (IdPs) such as Google Workspace, Microsoft Entra ID, and Okta,
+offering seamless Single Sign-On (SSO) for your users.
+
+It also supports social logins including Google, GitHub, and Microsoft accounts.
+
+For other OIDC (OpenID Connect)-compliant IdPs like Authentik, Keycloak, JumpCloud, and others, NetBird provides full support,
+though some additional configuration is required to complete the integration.
+
+<Note>
+    This guide covers the setup for cloud-hosted NetBird. If you are using the self-hosted version, please refer
+    to the [self-hosted documentation](/selfhosted/identity-providers).

+
+If you're using Google Workspace, Microsoft Entra ID, or a supported social login, you can simply sign in with no extra
+setup—just click the appropriate button on the [login page](https://app.netbird.io/):
