Okta Error "Your Organization doesn't support SMS or Voice Authentication at this time."

An authentication error occurs when users attempt to use Short Message Service (SMS) or Voice services for authentication. This occurs because organizations must bring a telephony provider to send SMS and voice messages starting September 15, 2024. To resolve this issue, use higher assurance authenticators and review the official notice for bringing a telephony provider. When attempting to use SMS or Voice services through Okta, the following error occurs:

Your Organization doesn't support SMS or Voice Authentication at this time.

• Okta Identity Engine (OIE)
• Okta Classic Engine
• Multi-Factor Authentication (MFA)
• SMS
• Voice

Starting September 15, 2024, organizations must bring a telephony provider at the time of renewal to send SMS and voice messages.

How is the SMS or Voice authentication error resolved?

Okta recommends that organizations consider higher assurance authenticators such as Okta Verify, FastPass, or FIDO2 WebAuthn and move away from SMS and Voice for authentication purposes.
