Microsoft urges Entra ID admins to replace SMS and voice with passkeys
Original title: Microsoft Urges Entra ID Admins to Migrate from SMS and Voice Authentication to Passkeys
Retirement of Microsoft-provided phone authentication starts February 1, 2027, in Worldwide and Government Community Cloud tenants.
Microsoft told Entra ID administrators, in Message Center notice MC1528000 on October 27, to move off Microsoft-provided SMS and voice authentication before retirement begins on February 1, 2027. Users who already have another sign-in method can keep using it. Users whose only method is SMS or voice may use it once more, then must register a passkey. The change does not ban all phone authentication; organizations can use a customer-managed telecom provider.
- Retirement should finish in early February 2027.
- Customer-managed provider configuration is due to be available from October 30, 2026.
- Existing customer-managed providers are unaffected.
- Tenants that do not use Microsoft-provided SMS or voice need no action.
- Passkeys use FIDO public-key cryptography and are bound to the site or app.
Impact: Phishable codes or SIM-swapped numbers used for sign-in
