Microsoft is making a major security change for personal accounts by gradually phasing out SMS text codes for account sign-ins and recovery. The move affects millions of users who rely on services like Microsoft accounts for Xbox, Windows 11, Outlook, OneDrive, and other consumer services.
The company says SMS-based authentication has become one of the biggest weak points in account security, especially due to the rise of SIM-swapping attacks and mobile carrier network breaches.
Importantly, this change currently applies only to personal Microsoft accounts. Work and school accounts managed through organizations are not affected for now.
Why Microsoft Is Moving Away From SMS Codes
For years, SMS verification codes were considered a convenient way to add an extra layer of security. However, cybercriminals have increasingly exploited weaknesses in mobile networks to intercept these codes.
According to Microsoft, attackers commonly use:
- SIM-swapping scams to hijack phone numbers
- Mobile carrier vulnerabilities
- Social engineering attacks targeting telecom providers
- Phishing methods that trick users into sharing SMS codes
Because of these risks, Microsoft is now pushing users toward more secure and phishing-resistant authentication methods.
Microsoft Recommends These Alternatives
Instead of relying on text messages, Microsoft wants users to set up the following security options:
Passkeys
Passkeys are becoming Microsoft’s preferred login method. These use built-in device security like fingerprint scanners, facial recognition, or PIN authentication for faster and safer sign-ins.
Users will soon see a new “Sign in faster” prompt during login that encourages passkey creation.
Benefits of passkeys include:
- No passwords to remember
- Strong protection against phishing attacks
- Faster one-tap sign-ins
- Works across modern phones, PCs, and browsers
Verified Backup Email
Microsoft also recommends adding a verified backup email address to make account recovery easier and safer if access is lost.
Microsoft Authenticator App
The Microsoft Authenticator app remains one of the safest alternatives to SMS verification. It generates secure login approvals and authentication codes directly on your device.
What This Means for Users
While SMS support may not disappear overnight, Microsoft is clearly signaling that text-based verification is no longer considered secure enough for the future.
Users who continue depending only on phone-based verification could eventually face limited recovery options or stronger prompts to switch to modern authentication methods.
This change also aligns Microsoft with broader industry trends, as companies including Google and Apple increasingly adopt passkeys as the next generation of secure authentication.
How to Prepare Your Microsoft Account
If you use a personal Microsoft account, it’s a good idea to:
- Set up a passkey on your phone or PC
- Install and configure Microsoft Authenticator
- Add a verified backup email address
- Review your account recovery methods
- Remove outdated or unused phone numbers
These changes can significantly reduce the risk of unauthorized access and improve account recovery security.
