When you add a guest user to your directory, the guest user account has a consent status (viewable in PowerShell) that's initially set to **PendingAcceptance**. This setting remains until the guest accepts your invitation and agrees to your privacy policy and terms of use. After that, the consent status changes to **Accepted**, and the consent pages are no longer presented to the guest.

> - **Starting July 12, 2021**, if Microsoft Entra B2B customers set up new Google integrations for use with self-service sign-up for their custom or line-of-business applications, authentication with Google identities won't work until authentications are moved to system web-views.

> - **Starting September 30, 2021**, Google is [deprecating embedded web-view sign-in support](https://developers.googleblog.com/2016/08/modernizing-oauth-interactions-in-native-apps.html). If your apps authenticate users with an embedded web-view and you're using Google federation with [Azure AD B2C](/azure/active-directory-b2c/identity-provider-google) or Microsoft Entra B2B for [external user invitations](google-federation.md) or [self-service sign-up](identity-providers.md), Google Gmail users won't be able to authenticate.

> - The [email one-time passcode feature](one-time-passcode.md) is now turned on by default for all new tenants and for any existing tenants where you didn't explicitly turn it off. When this feature is turned off, the fallback authentication method is to prompt invitees to create a Microsoft account.
