On October 30, 2026, Choose Your Own Telephony Provider (CYOT) became generally available for Microsoft Entra ID workforce tenants in global Azure, according to Microsoft’s current FAQ. Organizations can connect a supported provider to deliver SMS and voice verification codes.
Who it helps
Small-business owners whose employees use Entra ID and whose teams include people needing phone verification. The takeaway: choosing a provider does not remove responsibility for the business’s own integration.
The CYOT overview separates responsibilities: Entra generates and validates one-time codes, the provider delivers the message or call, and the integration runs in the organization’s Azure subscription. The business operates that integration and manages its provider account. Budget for provider charges and Azure resources separately; general availability does not mean free usage.
Before changing work sign-in
Our proposed review:
- Identify who actually needs SMS or voice verification and name a technical owner.
- Ask the administrator to assess provider coverage, costs, fraud controls and recovery.
- Do not begin by switching the entire team. Microsoft’s setup guide calls for evaluating the integration before a gradual rollout. It also warns that policy changes affect existing SMS and voice users; preserve current production user targeting.
- Agree on success criteria and what to do if a code fails to arrive before launch.
Access and limits
CYOT does not support Entra External ID or Azure AD B2C; SMS is a verification method here, not a primary sign-in method. Microsoft recommends phishing-resistant methods such as passkeys and reserving phone methods for justified needs.
This is news about integration availability, not a recommendation to buy a service or a guarantee of uninterrupted delivery.
