Hi STU ADAMS

For personal Microsoft accounts, Microsoft is phasing out SMS as a method of authentication and account recovery. You can learn more in the official Microsoft Support article: Microsoft to stop sending SMS codes for personal accounts.

In addition, Microsoft states that, for increased security, a new phone number can no longer be added as a sign-in verification method. Instead, I recommend using Microsoft Authenticator or another available verification method, such as a passkey or verified email.

To set up Microsoft Authenticator and enable two-step verification:

  • Sign in to your Microsoft account Security page.
  • Select Manage how I sign in.
  • Select Add a new way to sign in or verify, then choose Use an app.
  • Follow the prompts to set up Microsoft Authenticator.
  • Under Additional security, turn on Two-step verification.

I hope this clarifies the available verification options.
