Authentication
With Microsoft Entra External ID, you can create secure, customized sign-in experiences for your consumer- and business customer-facing apps. In an external tenant, there are several ways for users to sign up for your app. They can create an account using their email and either a password or a one-time passcode. Or, if you enable sign-in with Facebook, Google, Apple, a Microsoft Entra ID tenant, or a custom OIDC or SAML/WS-Fed identity provider (IdP), users can sign in using their credentials in the external identity provider. A user object is created for them in your directory with the identity information collected during sign-up.
