Sign-in options for Microsoft accounts in Azure Active Directory
The Microsoft 365 sign-in page for Azure Active Directory (Azure AD) supports work or school accounts and Microsoft accounts, but depending on the user's situation, it could be one or the other or both. For example, the Azure AD sign-in page supports:
- Apps that accept sign-ins from both types of account
- Organizations that accept guests
You can tell if the sign-in page your organization uses supports Microsoft accounts by looking at the hint text in the username field. If the hint text says "Email, phone, or Skype", the sign-in page supports Microsoft accounts.
Additional sign-in options work only for personal Microsoft accounts but can't be used for signing in to work or school account resources.
