86 days left — Feb 01, 2027
- What stops working
- Entra's built-in SMS and voice-call second factors are retired on February 1, 2027.
- Who is affected
- Tenants with users still verifying by SMS or phone call.
- Official migration path
- Move users to Microsoft Authenticator, passkeys or other supported methods.
- What the official path does not cover
- User-by-user re-enrollment; service accounts and shared mailboxes relying on phone factors need a different design.
