Update from Microsoft

We’re enabling a stronger form of multifactor authentication beginning September 15, 2023

On September 15, 2023, we’ll begin prompting your users who authenticate using SMS and voice methods to set up the Microsoft Authenticator app when they sign in to their work or school account. This change will take place on a rolling basis over six weeks as part of ongoing efforts to improve security.

This change will affect Microsoft Entra ID (previously Azure Active Directory) tenants that have the registration campaign feature set to the Microsoft managed state. After we enable the feature, users will be prompted to install the Microsoft Authenticator app, a stronger form of multifactor authentication than SMS and voice methods.

Recommended action

After the registration campaign feature is enabled, everyone in your organization who currently uses SMS or voice authentication will need to set up Microsoft Authenticator. To avoid any confusion, let your users know what to expect by September 15, 2023:

• When they sign in to their work or school account, they’ll see a prompt to set up the Authenticator app—they can choose to install it or skip the prompt. They can skip up to three times before they’re required to install it.
• To install it, they’ll need to select Next on the prompt, which will take them through the Authenticator app setup.
