Azure Active Directory B2C is deprecating login.microsoftonline.com
Updated: 04 December, 2019
On 4 December 2020, the login.microsoftonline.com endpoint will be deprecated for accessing B2C tenants. Existing tenants will need to move onto B2Clogin.com before that date, and all functionality will remain the same on the B2Clogin.com endpoint. See how to migrate your applications and web APIs to use B2Clogin.com.
New tenants created after this announcement will no longer be able to accept requests from login.microsoftonline.com. This doesn’t affect Azure Active Directory (Azure AD) tenants and is only for Azure Active Directory B2C tenants.
